Luke 23:34 Then said Jesus, Father, forgive them; for they know not what they do. And they parted his raiment, and cast lots.
If we learned to forgive as the Bible teaches us no doubt we would see more people believe on Him because of our testimony. Forgiving shows the world that we have learned something from our God that makes us very different.
Colossians 3:13 Forbearing one another, and forgiving one another, if any man have a quarrel against any: even as Christ forgave you, so also do ye.
Ephesians 4:32 And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ’s sake hath forgiven you.
