The apostle Paul wrote: “Become kind to one another, tenderly compassionate, freely forgiving one another just as God also by Christ freely forgave you.” (Eph. 4:32)
... Stressing this point, Jesus added: “For if you forgive men their trespasses, your heavenly Father will also forgive you; whereas if you do not forgive men their trespasses, neither will your Father forgive your trespasses.” (Matt. 6:14, 15)
