The bible says in Proverbs 28:9, God does not listen to our prayers if we intend to go back to our sin as soon as we get off our knees. If we want to forsake our sin and follow Him, however, He willingly listens—no matter how bad our sin has been. What closes His ears is not the depth of our sin, but our secret intention to do it again. God hears our intentions as clearly as He hears our words.
