Rev 4:1 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.I think it is Jesus Christ.But what confused me about this is that "The Man Child of Christ" Jesus is Christ
John had the task of writing of things in Rev 1:19 Write the things which thou hast seen, and the things which are, and the things which shall be hereafter. There are many that suppose Rev 12:5 is a parenthesis inserted pointing back to Jesus, and it ain't so. When Rev 4:1 said the things he sees will be hereafter from the time he saw it, I believe it and then must determine who the man child is other than Jesus. No other scripture I know of shows the catching up of the 144,000.
