The Bible defines a sharp contrast between a redeemed and transformed mind, and one still stuck in sin and self.  Before salvation, we walked in "futility of mind", but after, we are given a new mind.  Now, we are called to choose to have our mind "renewed" daily, eradicating anything of our old life, and investing into righteousness.  Video of this service is also available:  https://www.youtube.com/watch?v=vbZ-ZvH4eNc&t=3278s
