For we that are in this tabernacle do groan, being burdened: not that we would be unclothed, but clothed upon, that mortality might be swallowed up of life.
All Commentaries on 2 Corinthians 5:4 Go To 2 Corinthians 5
Irenaeus of Lyons
AD 202
How is it possible, therefore, that that seed should be after images of the angels, seeing it has obtained a form after the likeness of men? Why, again, since it was of a spiritual nature, had it any need of descending into flesh? For what is carnal stands in need of that which is spiritual, if indeed it is to be saved, that in it it may be sanctified and cleared from all impurity, and that what is mortal may be swallowed up by immortality;.
Still further did He also make it manifest, that we ought, after our calling, to be also adorned with works of righteousness, so that the Spirit of God may rest upon us; for this is the wedding garment, of which also the apostle speaks, "Not for that we would be unclothed, but clothed upon, that mortality might be swallowed up by immortality.".
This earnest, therefore, thus dwelling in us, renders us spiritual even now, and the mortal is swallowed up by immortality.
He who has perfected us for this very thing is God, who also has given unto us the earnest of the Spirit."
