Revelation 3:8

"For a great door and effectual is opened unto me, and there are many adversaries."

"Withal praying also for us, that God would open unto us a door of utterance, to speak the mystery of Christ, for which I am also in bonds:"

"And to the angel of the church in Philadelphia write; These things saith he that is holy, he that is true, he that hath the key of David, he that openeth, and no man shutteth; and shutteth, and no man openeth;"

"I can do all things through Christ which strengtheneth me."

"Furthermore, when I came to Troas to preach Christ's gospel, and a door was opened unto me of the Lord,"

"And when they were come, and had gathered the church together, they rehearsed all that God had done with them, and how he had opened the door of faith unto the Gentiles."

"But he that denieth me before men shall be denied before the angels of God."

"I know thy works, and where thou dwellest, even where Satan's seat is: and thou holdest fast my name, and hast not denied my faith, even in those days wherein Antipas was my faithful martyr, who was slain among you, where Satan dwelleth."

"I have manifested thy name unto the men which thou gavest me out of the world: thine they were, and thou gavest them me; and they have kept thy word."

"I know thy works, that thou art neither cold nor hot: I would thou wert cold or hot."
