2 Corinthians 3:18 (AMP)

18 And all of us, as with unveiled face, [because we] continued to behold [in the Word of God] as in a mirror the glory of the Lord, are constantly being transfigured into His very own image in ever increasing splendor and from one degree of glory to another; [for this comes] from the Lord [Who is] the Spirit.

Romans 12:2 (NLT)

2 Don’t copy the behavior and customs of this world, but let God transform you into a new person by changing the way you think.
