"For if you forgive other people when they sin against you, your heavenly Father will also forgive you."NIV
"For if ye forgive men their trespasses, your heavenly Father will also forgive you."KJV
To forgive those who have wronged us is not a natural inclination for us. But, the Lord says we are to forgive others or else we will not be forgiven. To forgive others is to put away any wrong they have done and never bring it back. That's what our Lord does with our sins. He throws them to the bottom of the ocean and remembers them no more. We all need forgiveness, so we also need to learn to forgive.
Heavenly Father, we ask for humble hearts to forgive those who have wronged us and hurt us. Make us aware of our own wrongs so that we can confess them and ask for Your forgiveness. We pray in Jesus' name, Amen.
