When the harvest has been gathered All my work is done When the last mile's been traveled And I've sung my final song If I'm called to give an answer At heaven's judgment seat Then let the blood of Calvary speak for me. There may be some friends who'll witness And speak a word so kind But their voice would seem so feeble At such an awesome time But there's a voice that calls for mercy Ringing thru eternity Just let the blood of Calvary speak for me May He write me down as righteous Where no righteousness has been Shielding me from wrath and judgment As it covers all my sin There's no work that I've accomplished Nor my goodness would I plead Just let the blood of Calvary speak for me.
