transformed — inward, with external manifestation
renewing of your mind — adjustment
good — beneficial
acceptable — pleasing to God

But we all, with unveiled face, beholding as in a mirror the glory of the Lord, are being transformed into the same image from glory to glory, just as by the Spirit of the Lord (2 Corinthians 3:18). The Spirit accomplishes the transformation with our cooperation.
For we ourselves were also once foolish, disobedient, deceived, serving various lusts and pleasures, living in malice and envy, hateful and hating one another. But when the kindness and the love of God our Savior toward man appeared, not by works of righteousness which we have done, but according to His mercy He saved us, through the washing of regeneration and renewing of the Holy Spirit (Titus 3:3-5).
