Psalms 51:13-15

Then I can show other guilty ones how loving and merciful you are. They will find their way back home to you, knowing that you will forgive them. O God, my saving God, deliver me fully from every sin, even the sin that brought bloodguilt. Then my heart will once again be thrilled to sing the passionate songs of joy and deliverance! Lord God, unlock my heart, unlock my lips, and I will overcome with my joyous praise!
