Do you know the best time to confess your sins?

As soon as you know that you have done wrong! You don't have to be afraid that God will not forgive you. He promises to forgive you right away, no matter what the sin may be, This is why He gave His life's blood on he cross- to cleanse you from all sin. To confess also means to be sorry for it. When you tell your sin to the Lord Jesus, ask Him to help you not to do it again.

Lamentations 3:22-23

22. Through the Lord's mercies we are not consumed, because His compassions fail not.

23. They are new every morning; Great is Your faithfulness.
