Then Peter came to Jesus and asked, “Lord, how many times shall I forgive my brother or sister who sins against me? Up to seven times?” Jesus answered, “I tell you, not seven times, but seventy-seven times. “Therefore, the kingdom of heaven is like a king who wanted to settle accounts with his servants. As he began the settlement, a man who owed him ten thousand bags of gold was brought to him. Since he was not able to pay, the master ordered that he and his wife and his children and all that he had be sold to repay the debt. “At this the servant fell on his knees before him. ‘Be patient with me,’ he begged, ‘and I will pay back everything.’ The servant’s master took pity on him, canceled the debt and let him go. “But when that servant went out, he found one of his fellow servants who owed him a hundred silver coins. He grabbed him and began to choke him. ‘Pay back what you owe me!’ he demanded. “His fellow servant fell to his knees and begged him, ‘Be patient with me, and I will pay it back.’ “But he refused. Instead, he went off and had the man thrown into prison until he could pay the debt. When the other servants saw what had happened, they were outraged and went and told their master everything that had happened. “Then the master called the servant in. ‘You wicked servant,’ he said, ‘I canceled all that debt of yours because you begged me to. Shouldn’t you have had mercy on your fellow servant just as I had on you?’ In anger his master handed him over to the jailers to be tortured, until he should pay back all he owed. “This is how my heavenly Father will treat each of you unless you forgive your brother or sister from your heart.” (Matthew 18:21-35)
Our heavenly Father will hand us “over to the jailers to be tortured” unless we forgive our brother or sister from our heart. The “torture” might include physical sickness. This leads us to James 5 where we are taught about the condition for receiving from the Lord healing from sickness.
Is anyone among you sick? Let them call the elders of the church to pray over them and anoint them with oil in the name of the Lord. And the prayer offered in faith will make the sick person well; the Lord will raise them up. If they have sinned, they will be forgiven. Therefore confess your sins to each other and pray for each other so that you may be healed. The prayer of a righteous person is powerful and effective. (James 5:14-16)
The condition is the forgiveness of our sins. Our sins can be forgiven when we as believers confess our sins to each other, forgive one another and are reconciled to one another. In that way our Father forgives us, and then we can be healed.
And when you stand praying, if you hold anything against anyone, forgive them, so that your Father in heaven may forgive you your sins.” (Mark 11:25)
