Once in sin's darkest night I was wand'ring alone A stranger to mercy I stood But the Savior came nigh When He heard my faint cry And He put my sins under the blood They are covered by the blood They are covered by the blood My sins are all covered by the blood My iniquities so vast Have been blotted out at last My sins are all covered by the blood From the burden I carried now I am set free For Jesus has lifted my load O the love and the grace I received in its place When He put my sins under the blood I can ne'er understand why he sought even me Why His lifeblood on calvary flowed But sufficient for me, Since He died on the tree He has put my sins under the blood They are covered by the blood They are covered by the blood My sins are all covered by the blood My iniquities so vast Have been blotted out at last My sins are all covered by the blood My iniquities so vast Have been blotted out at last My sins are all covered by the blood My sins are all covered by the blood
