A.T. Robertson Commentary 2 Corinthians 5

If--be dissolved (εαν--καταλυθη). Third class condition, εαν and first aorist passive subjunctive. The very word used (καταλυω) for striking down a tent.

The earthly house of our tabernacle (η επιγειος ημων οικια του σκηνους). Rather, "If our earthly (see on 1 Corinthians 15:40 for επιγειος) house of the tent (σκηνος, another form of σκηνη, tent, from root σκα, to cover)." Appositive genitive, the house (οικια) is the tent.

We have (εχομεν). Present indicative. We possess the title to it now by faith. "Faith is the title-deed (υποστασις) to things hoped for" (Hebrews 11:7).

A building from God (οικοδομην εκ θεου). This οικοδομη (found in Aristotle, Plutarch, LXX, etc., and papyri, though condemned by Atticists) is more substantial than the σκηνος.

Not made with hands (αχειροποιητον). Found first in Mr 14:58 in charge against Jesus before the Sanhedrin (both the common verbal χειροποιητον and the newly made vernacular αχειροποιητον, same verbal with α privative). Elsewhere only here and Col 2:11. Spiritual, eternal home.

To be clothed upon with our habitation which is from heaven (το οικητηριον ημων το εξ ουρανου επενδυσασθα). First aorist middle infinitive of late verb επενδυω, double compound (επ, εν) to put upon oneself. Cf. επενδυτης for a fisherman's linen blouse or upper garment (John 21:7). Οικητηριον is old word used here of the spiritual body as the abode of the spirit. It is a mixed metaphor (putting on as garment the dwelling-place).

Being clothed (ενδυσαμενο). First aorist middle participle, having put on the garment.

Naked (γυμνο). That is, disembodied spirits, "like the souls in Sheol, without form, and void of all power of activity" (Plummer).

Not for that we would be unclothed (εφ' ω ου θελομεν εκδυσασθα). Rather, "For that (εφ' ω) we do not wish to put off the clothing, but to put it on" (αλλ' επενδυσασθα). The transposition of the negative ου weakens the sense. Paul does not wish to be a mere disembodied spirit without his spiritual garment.

That what is mortal may be swallowed up of life (ινα καταποθη το θνητον υπο της ζωης). "Only what is mortal perishes; the personality, consisting of soul and body, survives," (Plummer). See on 1:22 for "the earnest of the spirit."

At home in the body (ενδημουντες εν τω σωματ). Rare verb ενδημεω from ενδημος (one among his own people as opposed to εκδημος, one away from home). Both εκδημεω (more common in the old Greek) and ενδημεω occur in the papyri with the contrast made by Paul here.
