" But if you do not forgive, neither will your Father in heaven forgive your failings and shortcomings. —MARK 11:25–26 One of the greatest reasons why prayer isn’t answered among Christians is unforgiveness. Jesus gave His disciples a command to forgive, and then He told them plainly that if they did not forgive, neither would their Father in heaven forgive them their failings and shortcomings. "
