So far has He removed our transgressions from us. As a father pities his children, So the Lord pities those who fear Him. NKJV God forgives sin out of His own nature and character. He forgives, because He loves us and wants to forgive. What is more exciting is that while we may forgive because God commands us to, we will find the more we forgive others, the more it builds our own character and the more we want to forgive and forget and move on in life.
Forgiveness of sin is a choice.
Following this path will produce great blessings in our lives. We are to forgive, because we come to love others as God loves us. NKJV God forgave us through Christ. We are to forgive others in the same fashion. When we rely upon Christ for our strength, He gives us the power to forgive in love.
