After repenting I say this to myself,
Show God that you are back on track by trying your best to be good and follow Him. Ignore the negative idea that you made a mistake so what’s the use in trying to be good because you did something bad, no one’s perfect; FOCUS on what you want-being good, clean and pure.
God doesn’t condemn you for making a mistake but is proud of you for repenting (I’m sorry please help me be better.) He’s proud of your faith in asking Him to help you. As you continue to pray and turn to Him, He will help you; His divine power will help you overcome your weaknesses and He will make you strong.
We all make mistakes. Thank goodness for repentance, the do-over that lets us try again.
