And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ’s sake hath forgiven you. Ephesians 4:32 KJV
This is what it means to walk in the law of Love. Treat others like you want to be treated.
After all, why in the world would you expect God to do what you are unwilling to do for others?
For if ye forgive men their trespasses, your heavenly Father will also forgive you: Matthew 6:14 KJV
But if ye forgive not men their trespasses, neither will your Father forgive your trespasses. Matthew 6:15 KJV
