Matthew 6: 14,15. (NIV) For if you forgive men when they sin against you, your heavenly Father will also forgive you. But if you do not forgive men their sins, your Father will not forgive your sins. Apparently if a christian holds a grudge against another and refuses to forgive them, the christian's sins will not be forgiven by God. Can an unforgiving Christian get to heaven without their sins being forgiven?
