Revelation 42

And so it is written, The first man Adam was made a living soul; the last Adam was made a quickening spirit. Howbeit that was not first which is spiritual, but that which is natural; and afterward that which is spiritual. The first man is of the earth, earthy: the second man is the Lord from heaven. As is the earthy, such are they also that are earthy: and as is the heavenly, such are they also that are heavenly. And as we have borne the image of the earthy, we shall also bear the image of the heavenly (1 Cor. 15:45-49).
Paul then added, "Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption." Something has to occur before "the image of the earthy" can be changed into "the image of the heavenly." The something that has to occur is an apocalyptic event where the dying of the image of the earthly dependency brings forth the life of the image of the heavenly reliance. In every apocalyptic event, the participant will be changed. Unfortunately, those who do not respond appropriately their lives will become more overwhelmed with stress, despair, or a sense of being forsaken and destroyed (2 Cor. 4:8-9). Paul simply stated, "Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed:" the image of the heavenly will come forth or the image of the earthly will be enhanced.
