Do you acknowledge your wicked deeds? or do you attempt to justify your actions?
You can pass the blame onto someone else or onto circumstances that you feel are beyond your control. You can say, "It's not really that bad!" and then forget about what you have done.
Or, you can take full responsibility for your actions, "Yes, I did it. Yes, I deserve hell for it. Lord, help me not to do it again!"
God loves to honour prayers like that! He will justify you through Christ and give you the strength to repent.
