14 “For if you forgive men their trespasses, your heavenly Father will also forgive you. 15 But if you do not forgive men their trespasses, neither will your Father forgive your trespasses” (Matthew 6:14–15, NKJV).
Jesus makes it very clear that our forgiveness is conditional. The little word “if” carries much weight. It directs attention to personal responsibility to do something to be forgiven by God. Namely, if we forgive others, our Father will forgive us. If not, then God will not forgive us. Jesus did not say to only forgive your brethren, but “men” (anthropos, person, human being). The gospel teaches Christians to put on hearts of forgiveness (Col. 3:12-13). Christ’s sermon to this point has repeatedly called on kingdom citizens to have a heart that is ready to forgive (Matt. 5:7, 9, 23-24, 39-42, 44). To withhold forgiveness brings punishment from God, not blessing (remember the unforgiving servant, Matt. 18:27-35). If we do not forgive from the heart, we will be punished, too (Matt. 18:35). Now, since forgiveness is conditional, why is there such objection when the gospel tells us of other conditions we must meet to be forgiven by God? The gospel says faith and confession of faith in Jesus, repentance, and baptism are conditions sinners must meet to be forgiven by God (John 8:24; Rom. 10:9-10; Luke 13:3, 5; Mark 16:16; Acts 2:37-38). So, it is false and futile to say salvation (forgiveness, remission of sins) is unconditional. Instead, we ought to be asking ourselves, do I have faith to submit to God’s conditions to be forgiven of my sins?
