For if you forgive men their trespasses, your heavenly Father will also forgive you. But if you do not forgive men their trespasses, neither will your Father forgive your trespasses. (Matthew 6:14–15, NKJV)
Jesus applies the principle of sowing and reaping to forgiveness. Just as we reap what we sow, God’s forgiveness of us depends upon our forgiveness of those who sin against us. Here is a fundamental truth to remember: the hypocrite will not be forgiven. In this context, Jesus has been addressing the problem of hypocrisy in one’s spiritual life, and now He returns to it (Matt. 6:2, 5, 16). How hypocritical and futile to think that we have God’s forgiven when we ask Him for it, yet we refuse to give it to others when they ask for ours. If we hold bitterness and resentment in our hearts toward one who asks our forgiveness, instead of freely and immediately forgiving them from our heart, we will not be forgiven by God when we ask Him to forgive us. Allow this truth to sink deep into your heart so that it shapes your readiness to forgive those who sin against you (Col. 3:12-14).
