[Note:  These are the notes for a split sermon given to the United Church of God congregation in Portland, Oregon on Sabbath, August 22, 2026.]

Good morning brethren. One of the things you learn when you have to deal with other people on a close basis is that there are often very different thoughts about doors. My own personal philosophy of doors, such as it is, is that for interior doors I like open doors to be very open, wide open, and I like closed doors to be shut and locked or bolted, barred against entry. Other people like doors to be more ambiguous, where a closed door might not be locked and one does not know whether it is really closed or open, it may look closed but actually be open, or may look open but be closed and occupied. Whatever your opinion, though, what matters for the purposes of this message is that the Bible speaks about doors in very important passages, and it is worthwhile to us to be able to distinguish between an open and a closed door from God, and what it means. It is to that task that I now turn, beginning with the account of open and closed doors in the last two of the seven cities of Revelation 2 and 3.

Let us begin with the letter to Philadelphia, in Revelation 3:7-13: “And to the angel of the church in Philadelphia write: ‘The words of the holy one, the true one, who has the key of David, who opens and no one will shut, who shuts and no one opens. I know your works. Behold, I have set before you an open door, which no one is able to shut. I know that you have but little power, and yet you have kept my word and have not denied my name. Behold, I will make those of the synagogue of Satan who say that they are Jews and are not, but lie—behold, I will make them come and bow down before your feet, and they will learn that I have loved you. Because you have kept my word about patient endurance, I will keep you from the hour of trial that is coming on the whole world, to try those who dwell on the earth. I am coming soon. Hold fast what you have, so that no one may seize your crown. The one who conquers, I will make him a pillar in the temple of my God. Never shall he go out of it, and I will write on him the name of my God, and the name of the city of my God, the new Jerusalem, which comes down from my God out of heaven, and my own new name. He who has an ear, let him hear what the Spirit says to the churches.'”

Notice first who is speaking, because the identification comes before the promise. Jesus Christ introduces Himself here as the one who holds the key of David, and the key is an image of authority over a household. When Christ opens, the door stays open, and no human authority, no hostile synagogue, no imperial magistrate, and no rival congregation down the street can shut it. When Christ shuts, the door stays shut, and no amount of pushing, lobbying, or self-promotion will get it open. That is the first thing to fix in our minds. A door in Scripture is not a neutral opening; it is an opening that somebody controls. The question is never merely whether a door is open but who opened it.

Notice second what qualifies Philadelphia for this open door. It is not strength. Christ says plainly that they have little power. In a modern congregation we would call that a small budget, a small hall, a thin roster of people willing to serve, and no leverage in the surrounding city. What they have instead is that they kept His word and did not deny His name. The open door is set before a congregation whose only assets are faithfulness and endurance. This is worth sitting with, because we naturally assume that God opens doors to the impressive and shuts them to the weak. Philadelphia says the opposite. The open door is a gift to the faithful and weak, and the weakness is part of the point, because a door held open by Christ does not need to be propped open by us.

Notice third what the open door is for. The letter does not spell it out in a single phrase, and commentators have taken it two ways, both of which are consistent with the rest of Scripture. It is a door of entrance into the kingdom, an assurance that these people will not find themselves locked out at the end. And it is a door of opportunity, a field of labor set before a small congregation that could never have opened it for itself. The promises that follow lean toward the first: preservation through the hour of trial, a pillar in the temple, a new name written. But the pattern of the apostolic writings, which we will come to shortly, leans toward the second. I would suggest that we do not need to choose. The same Christ who opens the door of the kingdom to us opens the door of work in front of us, and He does both by the same authority.

Now let us turn to the very next letter, to Laodicea, in Revelation 3:14-22: “And to the angel of the church in Laodicea write: ‘The words of the Amen, the faithful and true witness, the beginning of God’s creation. I know your works: you are neither cold nor hot. Would that you were either cold or hot! So, because you are lukewarm, and neither hot nor cold, I will spit you out of my mouth. For you say, I am rich, I have prospered, and I need nothing, not realizing that you are wretched, pitiable, poor, blind, and naked. I counsel you to buy from me gold refined by fire, so that you may be rich, and white garments so that you may clothe yourself and the shame of your nakedness may not be seen, and salve to anoint your eyes, so that you may see. Those whom I love, I reprove and discipline, so be zealous and repent. Behold, I stand at the door and knock. If anyone hears my voice and opens the door, I will come in to him and eat with him, and he with me. The one who conquers, I will grant him to sit with me on my throne, as I also conquered and sat down with my Father on his throne. He who has an ear, let him hear what the Spirit says to the churches.'”

Here is the reversal, and it is a sharp one. In Philadelphia, Christ holds the key and opens the door and stands inside the household as its master. In Laodicea, Christ is outside on the step, knocking. The congregation that thought it needed nothing had managed to shut the door on the only one who could give it anything. And the door He asks them to open is not the door of the city or the door of the assembly hall. He addresses an individual: if anyone hears my voice and opens the door. A whole congregation can be lukewarm while individual members within it still hear the knock and answer.

Consider what Laodicea had that Philadelphia lacked. Laodicea had money, a banking reputation, a textile trade in black wool, and a medical school known for eye ointment. Christ answers each of those in turn: buy gold from me, buy white garments from me, buy salve from me. Everything they were proud of, He offers to replace with the genuine article. And what Philadelphia had that Laodicea lacked was the honest knowledge of its own littleness. Philadelphia knew it had but little power. Laodicea said it needed nothing. That self-assessment is the hinge of the whole letter, because a congregation that believes it needs nothing will not answer a knock at the door. Why would you? You have everything already.

I want to be careful here, because it is very easy to preach Laodicea at other people and very hard to hear it about ourselves. The lukewarm condition is not described as scandalous sin. There is no accusation of idolatry, immorality, or false doctrine in this letter. There is only a comfortable, self-satisfied adequacy that has quietly locked the door and gone about its business. That is a condition that arrives without announcing itself. And notice the tone of Christ’s response: those whom I love, I reprove and discipline. The knock is not a threat. It is an act of affection from someone who wants to come in and share a meal, which in that culture meant fellowship and welcome and a long evening at the table, not a quick inspection.

So we have two doors in adjoining letters. One that Christ opens and holds open before a weak and faithful congregation, and one that a proud congregation has closed against Him and that He waits patiently outside of. And these two images are held together by a third, which is Christ’s own statement about Himself in John 10:1-10: “Truly, truly, I say to you, he who does not enter the sheepfold by the door but climbs in by another way, that man is a thief and a robber. But he who enters by the door is the shepherd of the sheep. To him the gatekeeper opens. The sheep hear his voice, and he calls his own sheep by name and leads them out. When he has brought out all his own, he goes before them, and the sheep follow him, for they know his voice. A stranger they will not follow, but they will flee from him, for they do not know the voice of strangers.” This figure of speech Jesus used with them, but they did not understand what he was saying to them. So Jesus again said to them, “Truly, truly, I say to you, I am the door of the sheep. All who came before me are thieves and robbers, but the sheep did not listen to them. I am the door. If anyone enters by me, he will be saved and will go in and out and find pasture. The thief comes only to steal and kill and destroy. I came that they may have life and have it abundantly.”

Here Christ does not merely hold the key to the door. He is the door. And that changes what the whole image means. When we say that God has opened a door for us, we are not saying that a convenient set of circumstances has come together. We are saying that access to the Father, to the flock, and to the pasture runs through a person, and that person is Jesus Christ.

Two details in this passage deserve attention. The first is the voice. Sheep in that region were penned overnight in a common fold with other flocks, and in the morning each shepherd came and called, and his own sheep sorted themselves out and followed him. They did not follow the strangers, not because the strangers were obviously frightening, but because the voice was wrong. That is the same test we saw in Revelation 3. Philadelphia kept His word and did not deny His name. Laodicea had a Christ who was still speaking, still knocking, still calling, and the household had grown deaf enough to their own prosperity that they did not recognize the voice at the door. The ability to tell an open door from a closed one is, at bottom, the ability to recognize whose voice is speaking.

The second detail is what happens after you go through the door. The one who enters by Christ will be saved and will go in and out and find pasture. That is not an image of arrival and rest alone. Going in and out is the ordinary Hebrew way of describing a whole active life, going out to work in the morning and coming in at evening. A door in Scripture is not a destination. It is a passage into a life, and the life on the other side involves work and pasture and going out again tomorrow.

Which brings us to Paul, and to what an open door looks like in practice. Consider first Acts 16:6-10, which describes the closed doors that preceded Paul’s entry into Greece:

“And they went through the region of Phrygia and Galatia, having been forbidden by the Holy Spirit to speak the word in Asia. And when they had come up to Mysia, they attempted to go into Bithynia, but the Spirit of Jesus did not allow them. So, passing by Mysia, they went down to Troas. And a vision appeared to Paul in the night: a man of Macedonia was standing there, urging him and saying, ‘Come over to Macedonia and help us.’ And when Paul had seen the vision, immediately we sought to go on into Macedonia, concluding that God had called us to preach the gospel to them.”

Notice that Paul is stopped twice, and stopped from doing good things. Preaching in Asia was not a sin. Preaching in Bithynia was not a sin. These were closed doors, and no reason was given for closing them at the time. Paul does not sit down in Phrygia and wait for an explanation. He keeps moving until he finds an opening, and the opening turns out to be Europe. A closed door from God is not necessarily a rebuke, and it is very often not explained. It is simply a shut door, and the faithful response is to try the next one rather than to spend a year interrogating the hinges.

Then, when Paul later writes about that same city of Troas in 2 Corinthians 2:12-13, we get something even more instructive: “When I came to Troas to preach the gospel of Christ, even though a door was opened for me in the Lord, my spirit was not at rest because I did not find my brother Titus there. So I took leave of them and went on to Macedonia.”

Read that carefully, because it complicates every simple formula about doors. There was an open door. Paul says so directly, and he says it was opened in the Lord, which is to say it was a genuine opportunity from God and not merely a favorable market. And Paul walked away from it. He was anxious about the Corinthians, he was waiting on news from Titus, and he judged that he could not do the work in that state, so he left an open door standing open and went on to Macedonia.

Compare that with 1 Corinthians 16:8-9: “But I will stay in Ephesus until Pentecost, for a wide door for effective work has opened to me, and there are many adversaries.” At Ephesus the door was wide, the work was effective, and the opposition was fierce, and Paul stayed. At Troas the door was open and Paul left. The difference was not the size of the opportunity. It was Paul’s judgment about where he could actually serve the brethren, weighed under God, with a conscience that was not at rest.

Two lessons follow from this, and I think they are the practical heart of the matter. The first is that an open door is not the same thing as a command. God opens doors; He does not shove us through them like cattle. Paul exercised judgment in front of an open door, and Scripture records that judgment without condemning it. The second is the reverse: an open door is also not a guarantee of ease. The wide door at Ephesus came with many adversaries, mentioned in the same breath. If we have adopted the notion that an open door from God is one that opens smoothly and leads to pleasant work with agreeable people, the apostolic record does not support it. The presence of opposition tells us nothing about whether a door is from God. Very often it tells us the opposite of what we assume.

Notice as well that in the apostolic writings the open door is almost always a door for the word rather than a door for the man. Paul asks the Colossians to pray that God would open a door for the word, so that the mystery of Christ might be declared. In Acts, when Paul and Barnabas report to Antioch, they tell how God had opened a door of faith to the Gentiles. The door is not a career opportunity. It is an opening in a wall that had stood between people and the gospel, and God is the one who makes the opening.

So let us gather these together. Christ holds the key, and He opens and shuts, and neither our enemies nor our own cleverness can override Him. Christ is Himself the door, so that the whole question of access to the Father runs through a person and not through a procedure. Christ sets an open door before the weak and faithful, and He stands knocking outside the door of the strong and self-satisfied. And the doors He opens are openings for His word, which may be wide, may be attended by many adversaries, and may sometimes be laid down for the sake of the brethren.

What, then, do we do with all of this?

Begin by asking which door you are standing at. If you are in a Philadelphia moment, with little power and an opening in front of you that you did not create and could not have created, then go through it and do the work, and do not spend your strength trying to hold open what Christ is holding open for you. If you find yourself in a Laodicean moment, prosperous and adequate and needing nothing, then listen for the knock, because the knock is still an act of love and the offer to come in and eat is still on the table. And if you are standing in front of a door that is plainly shut, and no explanation has been given, then take Paul’s example and keep walking. The shut door in Bithynia was the reason the gospel reached Europe.

Above all, remember whose voice you are listening for. The sheep in that common fold did not sort themselves out by examining the doors. They sorted themselves out by hearing a voice they knew. Our ability to read our circumstances is limited and often wrong. Our ability to know the voice of the Shepherd, because we have kept His word and not denied His name, is the thing that will actually get us through the right door. He is the door. Everything else is a hinge.
