Lack of forgiveness is a dangerous thing...

As a Christian I embrace all doctrines of Christ of which forgiveness, restoration and reconciliation are essential.

Jesus said if you do not forgive then the Father will not forgive you.

That is a matter dependant upon salvation which most people tragically overlook.

For if ye forgive men their trespasses, your heavenly Father will also forgive you: But if ye forgive not men their trespasses, neither will your Father forgive your trespasses. Matthew 6:14-15 KJV
