The forgiveness of sins is very important in the life of mankind, God have instructed us to forgive one another. According to Scripture, all people have sinned, but God offers forgiveness through repentance and faith. If we read through the old testament the form of forgiveness is done through sacrifice, but Jesus Christ have made it easy for us in the new testament.
The Bible teaches that forgiveness is not something we can earn, but a gift from God. When we confess our sins sincerely, God is faithful to forgive and cleanse us.
*1 John 1:9, “If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
