If you are a true believer and have a personal relationship with God, you must have confessed Him about your sins, or prayed Him to forgive your sins which you may have comitted from time to time, knowingly or unknowingly. Then what was the answer from Him? How did God forgive your sins when you prayed? Please tell us your actual testimony and experience instead of any theory. Have you ever prayed God to forgive until He forgive you? I hope everyone can testify the actual experience, if she or he is a true believer in Lord Jesus Christ.
