Ephesians 4:17, 23
This I say, therefore, and testify in the Lord, that you should no longer walk as the rest of the Gentiles walk, in the vanity of their mind,…and be renewed in the spirit of your mind.
It is the way one’s mind works that distinguishes one from the ungodly. If we think like sinners, our walk will resemble theirs, and our destinies will be the same. That’s why the renewal of our minds is absolutely mandatory.
