A transformed mind
Christians need pure minds, that include a cleansed memory.
The hard drive of our minds need to be deleted from unclean thoughts. We need minds that are free from the horrible recollection of sin.
God wants us to download and store in our minds: GOOD things, PURE thoughts, TRUTHFUL ideas, with HONEST motives.
Remember, to think like the Lord, you've got to go where the mind of the Lord is recorded...the BIBLE!
Be ye transformed by the renewing of your mind!
