Can we stay in unforgiveness and still go to heaven? In Matthew 6, Jesus clearly says, "For if you forgive other people when they sin against you, your heavenly Father will also forgive you. But if you do not forgive others their sins, your Father will not forgive your sins." Forgiveness must be of utmost importance to God. Forgiveness is not weakness. It is not God making you the world's punching bag. Nor does holding unforgiveness give you power over the person who wronged you. The truth is, the person or thing you don't forgive, you will eventually become. Forgiveness is actually the most powerful thing Jesus could have you do. It causes you to start becoming like Him.
