Revelation 4:1

22 He that hath an ear, let him hear what the Spirit saith unto the churches.

1 After this I looked, and, behold, a door was opened in heaven: and the first voice which I heard was as it were of a trumpet talking with me; which said, Come up hither, and I will shew thee things which must be hereafter.

Ver. 1. A door was opened in heaven ] That is, preparation was made for the manifestation of more heavenly mysteries.

Was as it were of a trumpet ] To reuse and raise up his attention. For it might fare with him as with a drowsy person, who though awaked, and set to work, is ready to sleep at it. Compare Zechariah 4:1 .

Come up hither ] Not by local motion, but by mental illumination.

I will show thee ] That thou mayest show the Church, that they have a most glorious and almighty deliverer.
