So he drove out the man; and he placed at the east of the garden of Eden Cherubims, and a flaming sword which turned every way, to keep the way of the tree of life [Gen. 3:24].
"This does not mean that God put up a roadblock. It means that the way of life was kept open for man to come to God. But now that way is not through the tree of life. Salvation must come through a sacrifice, and when man looked back, the blood of the sacrifice is what he saw." McGee, J. V. (1997). Thru the Bible commentary (electronic ed., Vol. 1, p. 28).

For as the lightning cometh out of the east, and shineth even unto the west; so shall also the coming of the Son of man be [Matt. 24:26–27].
"He comes, there will not be any John the Baptist to announce Him. But when He comes, the whole world will know and it will be as public as lightning. Those of you that live in the Middle West know that a lightning storm is a public affair. When it comes, everybody knows about it, and sometimes it is a frightful experience. The Lord’s second coming to the earth will be like that. No one will need to announce it. When our Lord comes the second time to establish His Kingdom on earth, everyone will know He is coming. (Remember that His second coming to earth does not refer to the Rapture.)" McGee, J. V. (1991). Thru the Bible commentary: The Gospels (Matthew 14-28) (electronic ed., Vol. 35, p. 141).
