In Revelation 3 we read that the church in Philadelphia was a faithful church. The elder was faithful, and so the church was faithful. The Lord told them, I have put before you an open door which nobody can shut” (Rev. 3:8).
When the Lord opens a door for us nobody can shut it. He says, “I have the keys. I open and no man can shut” (Rev. 3:7). We don’t have to go banging away at any door. Our Lord opens the right ones for us, without our even touching them. They are like the automatic doors that we have seen in some airports that open as soon as you come near them. Are you looking for a door of ministry for yourself? Are you trying to open such a door for yourself or looking to some influential man to open that door for you? Are you coveting the ministry that someone else has? That is evil.
