4 Bible Verses about The Inner Man

Woe unto you, scribes and Pharisees, hypocrites! because you are like whitened sepulchers, which are beautiful indeed externally, but within they are full of the hones of the dead people, and every impurity. So you also appear unto the people indeed righteous, but within you are full of hypocrisy and iniquity.

Therefore we faint not; but if indeed our external man perishes, yet our internal man is renewed day by day.

and having put on the new man, who is renewed into perfect knowledge according to the image of him who created him:

But we all, with unveiled face beholding the glory of the Lord, are being transformed into the same image from glory to glory, even as by the Spirit of the Lord.
