2 Corinthians 4:16

διὸ οὐκ ἐγκακοῦμεν, ἀλλ' εἰ καὶ ὁ ἔξω ἡμῶν ἄνθρωπος διαφθείρεται, ἀλλ' ὁ ἔσω ἡμῶν ἀνακαινοῦται ἡμέρᾳ καὶ ἡμέρᾳ.

dio oyk egkakoymen, all' ei kai o exō ēmōn anthrōpos diaphtheiretai, all' o esō ēmōn anakainoytai ēmera kai ēmera.

King James Version (KJV)

For which cause we faint not; but though our outward man perish, yet the inward man is renewed day by day.

Modern English

Therefore we do not lose heart. Though outwardly we are wasting away, yet inwardly we are being renewed day by day.
