“Take heed to yourselves: If thy brother trespass against thee, rebuke him; and if he repent, forgive him. And if he trespass against thee seven times in a day, and seven times in a day turn again to thee, saying, I repent; thou shalt forgive him. And the apostles said unto the Lord, Increase our faith.” - Luke 17:3-5.
The Lord's Prayer also harps on forgiveness and that is why Jesus Christ taught us to pray that God should “forgive us our debts, as we forgive our debtors.” Since it is the duty of every one to obey God, anyone who violates His laws has incurred a debt, which can only be made good by repentance and right conduct. But being a merciful Father, and by virtue of His love for man, God Almighty forgives those who show remorse for their sins and repent. But for this quality of forgiveness, no man would be alive to serve God. David the prophet stated: “If thou, LORD, shouldest mark iniquities, O Lord, who shall stand? But there is forgiveness with thee, that thou mayest be feared.” (Psalm 130:3, 4) The other part of the prayer is that since God is ready to forgive us, we should also forgive those who wrong us. - Matthew 18:21-35.
