My heart is black within Stained by the filth of my sin Rotten is my mind Sin makes me blind The blood of Jesus spilled on the ground In this blood our salvation is found Cry out to the Lord, pray to Him Trust in God amidst your suffering Again I cry in the night Again and again I've tried to get rid of my sin But it stays, like slime it clings Only in the blood of the Lamb am I free It gives me strength, it justifies me The Lamb is my Lord, my righteousness Faith in Him I now confess I can not save myself Nor can my works or my wealth He who died on the cross for me, only He can set me free If we are not in our Lord Jesus, then God's wrath shall consume us So let us repent and turn to the Light For the day of judgement is nigh
