He who is born again, having the life and nature of God On the inside, has the same character as God does resident in him. That’s a good character. Develope it. Don’t listen to your head telling you anything else. For God has made you like himself; good.
2 Corinthians 5:17
17 Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new.
