That would be 'Blood of Christ, the Grace of God's Love.'
HEB 10:26-30
26If we deliberately keep on sinning after we have received the knowledge of the truth, no sacrifice for sins is left, 27but only a fearful expectation of judgment and of raging fire that will consume the enemies of God. 28Anyone who rejected the law of Moses died without mercy on the testimony of two or three witnesses. 29How much more severely do you think a man deserves to be punished who has trampled the Son of God under foot, who has treated as an unholy thing the blood of the covenant that sanctified him, and who has insulted the Spirit of grace? 30For we know him who said, "It is mine to avenge; I will repay,"[d] and again, "The Lord will judge his people."[e] 31It is a dreadful thing to fall into the hands of the living God.
