Actually it says in the Bible if we don’t forgive we won’t be forgiven. Jesus spoke this in Matthew just after Lords Prayer.
“If you forgive those who sin against you, your heavenly Father will forgive you. But if you refuse to forgive others, your Father will not forgive your sins” (Mat 6:14-15) Your post Do I have to forgive him? says it doesn’t matter if you do or not.
I think you misunderstood my answer. I didn’t say it doesn’t matter if you forgive someone or not. I said it doesn’t matter if you feel like forgiving someone or not, do it out of gratitude to the Lord who forgave you. Failure to forgive is a sin that can give the devil a foothold in your life.
Regarding Matt. 6:14-15, if you understand the doctrine of eternal security, you know Jesus wasn’t talking about our salvation there. He was talking about remaining in good standing with the Lord after we’ve been saved. We know this because a) forgiving others is not a precondition for salvation, and b) once we are saved we can’t become unsaved.
Believing in the Lord’s death as payment for all our sins is the only requirement for salvation (1 Cor. 15:1-4) and when we believe that, God puts His seal of ownership on us, and puts His spirit in our heart as a deposit guaranteeing what is to come (2 Cor. 1:21-22).
