Ephesians 4:23
Be Renewed In The Spirit of Your Mind! You can renew that book.
The concept of renewing a book at a library is a very common practice for many people. You've borrowed a book, its time to return it, but you're not done reading it, so you choose to renew the loan. Similarly, God calls upon us to renew our minds daily.
Ephesians 4:20-24 "But you have not so learned Christ, if indeed you have heard Him and have been taught by Him, as the truth is in Jesus: that you put off, concerning your former conduct, the old man which grows corrupt according to the deceitful lusts, and be renewed in the spirit of your mind, and that you put on the new man which was created according to God, in true righteousness and holiness.
