And so it is written, “The first man Adam became a living being.” The last man Adam (Jesus Christ) became a life-giving spirit. Genesis 1:31, Romans 5:19,21
However, the spiritual is not first, but the natural and afterward the spiritual. The first man was of the earth made of dust; the second Man is the Lord from heaven. As was the man of dust, so also are those who are made of dust; and as heavenly Man, so also are those who are heavenly. And as we have borne the image of the man of dust, we shall also bear the image of the heavenly Man. Acts 1:11; Philippians 3:20,21; John 3:1-3
Now this I say brethren, that flesh and blood cannot inherit the kingdom of God; nor does corruption inherit incorruption. Behold, I tell you a mystery: See notes Romans 8:23
We shall not all sleep, but we shall all be changed—in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, (heralding the end of the church area, when all believers will be removed from the earth at the rapture; 1Thessalonians 4:16,17) and the dead will be raised incorruptible, and we shall be changed. For this corruptible must put on incorruption, and this mortal must put on immortality. So when this corruptible has put on incorruption and this mortal has put on immortality, then shall be brought to pass the saying that is written: Death is swallowed up in victory.”
“O Death, where is your sting?
O Hades, where is your victory?”
The sting of death is sin, and the strength of sin is the law. But thanks be to God, who gives us the victory through our Lord Jesus Christ.
Romans 3:23; 4:15; 6:23; Galatians 3:10-13; Isaiah 25-8, Hosea 13:14
Therefore, my beloved brethren, be steadfast, immovable, always abounding in the work of the Lord, knowing that your labor is not in vain in the Lord.
