1 Cor 15:50-54
50 Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.
51 Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed,
52 In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
53 For this corruptible must put on incorruption, and this mortal must put on immortality.
54 So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory.
Verse 50 is the reason that Christ comes back for the church, his bride, both of those who have fallen asleep (the dead) and of the living who remain alive. The church can not put on incorruption and immortality in heaven nor upon the earth. They must be raised and caught up together from the earth to meet the Lord in the air. It is in the air that Christ will have his rewards with Him. It is in the air that we will be changed from our vile bodies (Phil 3:21) and put on incorruption so that we can be prepared to inherit the kingdom of God and eternal life. This meeting in the air is the day of redemption for our bodies (Rom 8:23, Eph 1:14, 4:30), where we will receive our glorified bodies made like unto His. This does not take place in heaven from which the Lord descends nor on the earth from which we are raised. The bema seat judgment of Christ (2 Cor 5:10) happens in the clouds of the air, that is the setting. This is where we are rewarded or suffer loss as believers for the works done in our body of flesh, being tried and saved as by fire (1 Cor 3:13-15). Remember that the dead and living are raised up together, with their bodies, to meet the Lord in the air and not in heaven.

How have you concluded that putting on incorruption "must" take place in the air?
