In Matthew 6:12, Jesus taught His disciples to pray, “Forgive us our sins, as we have forgiven those who sin against us.” Jesus immediately explained why we must forgive those who have wronged us (vv.14-15). And He later illustrated it with a parable (Matthew 18:23-35).

How much did the first servant owe the master? Ten thousand talents (v.24 NIV). One talent was the equivalent of 20 years’ wages for an average worker. It would have taken 200,000 years for the servant to earn 10,000 talents. Although the servant promised to pay back everything (v.26), this was an impossible debt to repay. So “his master was filled with pity for him, and he released him and forgave his debt” (v.27).

How much did the fellow servant owe the first servant? One hundred denarii (v.28 NIV). Equivalent to 20 weeks of common labor. This debt could be repaid within 5 months. The fellow servant begged for some time to pay back this debt, but the first servant refused and had him put in prison instead (vv.29-30).

You are a free person. Jesus has set you free. But when you refuse to forgive, you become a prisoner again. A prisoner of your own unforgiveness. A prisoner of your own bitterness. A prisoner of sin again (vv.32-34). The worst kind of prison is the prison of an unforgiving heart.

In his book The Lord and His Prayer, N. T. Wright wrote: “Failure to forgive wasn’t a matter of failing to live up to a new bit of moral teaching. It was cutting off the branch you were sitting on. The only reason for being kingdom-people, for being Jesus’ people, was that the forgiveness of sins was happening; so if you didn’t live forgiveness, you were denying the very basis of your own new existence.”

If we are truly forgiven, we will be forgiving.
