HOW GOD HELPS US TO FORGIVE OTHERS
And forgive us our debts, as we forgive our debtors. Matthew 6:12

For some of us, we would rather believe God for something on a smaller scale, like climbing Mount Everest or swimming across the ocean. We know that we need God’s forgiveness for our sins, but why should we have to forgive those who have hurt us so deeply? Look at the definition of forgiveness, which is "to send forth, in various applications (as follow); forgive, forsake, lay aside, leave, let alone, let be, let go, send away." That is so beautiful when we look at our sins and believe that God will let them go, and send them away. He is God, and He can do all things. I am human, and therefore, I am limited. Since God can do all things, then He can help me do all things, especially the things that He requires me to do.

I can do all things through Christ which strengtheneth me. Philippians 4:13
When we as sinners are forgiven of our sins, the Savior Jesus Christ comes to live in our hearts. So, now a life that was once subject to all the works of the flesh (See Galatians:5:19-21 Adultery, fornication, uncleanness, lasciviousness, idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies, envyings, murders, drunkenness, revellings, and such like:), is now filled with the fruit of the Spirit:
But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, Meekness, temperance: against such there is no law. Galatians 5:22-23
Before I received Jesus into my heart, I was filled with the works of the devil, and that is exactly how I lived; sometimes I was a nice sinner, sometimes I was a bad sinner, but I was a sinner nonetheless. To put this in modern terms, my default setting was sin.
Now with Jesus in my heart, although I am not perfect, my life is filled with the fruits of the Spirit. I don't do everything right, but my default setting is righteousness or doing what is right and just. Now, instead of holding a grudge and being unforgiving, I am able to forgive others.
