The Bible tells us we must (not should...must!) forgive. The Bible tells us that God forgives forgivers. Conversely, God doesn't forgive those who won't forgive. If we refuse to forgive, we sin by not doing what we're told to do. Unforgiven sin will keep us from the presence of God and hinder our prayers. OK.... that seems pretty simple to follow. So, why is it that we keep asking God to hear our prayers and bless us when we know there are people we are holding grudges against?!
Do we think He doesn't know? Or maybe we think He knows you were wronged and that you have a right to hold that grudge and therefore He'll overlook it? Wrong!! God knows our thoughts, so we can't hide anything. And He tells us to forgive those who mistreat us, even our enemies!
We all need to search our hearts and forgive and release those we have been holding something against. When we do, we'll begin to see an outpouring of God's blessings on our lives.
