In Matthew 18:21-35, Jesus tells us the parable of the unforgiving servant. The king forgives him his debt because the servant is unable to pay it back. That same servant does not forgive the debt of a fellow servant. The kings discovers this deed. The king hands over the unforgiving servant to the torturers until he can pay it back.
Since the servant is unable to pay back the debt. Therefore, the servant will be forever tortured. Jesus relates the command to forgive others to our eternal salvation. We can never pay back our debt to God for our sins. Therefore, unforgiveness means hell, I think.
Is Jesus talking about the eternal consequences for us if we obstinately refuse to forgive another or any group?
I am not writing about having difficulty forgiving.
