being born of the Spirit of God ensures a smooth line of communication between you and God. Proverbs 20:27 tells us that the spirit of man provides the light through which man communicates and leads man.

Unlike Cain, a Christian has a new spirit (2 Corinthians 5:17) and can therefore determine what happens in his mind. He can rule over his mind by consistently feeding his spirit with the Word, that way his spirit has dominance over his mind. He can determine his thoughts (Philippians 4:8), and he can control how he reacts to his feelings (1 Corinthians 9:27).
