Yes, the blood of the LAMB. Sadhu Sundar Singh said: “Once a young man fell over a cliff. By the time he was rescued, he had lost so much blood that he was almost dead. His father rushed him to a doctor, but the doctor said, “He will certainly die, unless someone can be found who is willing to provide enough blood for a massive transfusion.” Now the father’s heart overflowed with such love for his son that he offered his own blood, though he knew it would cost him his own life. So by the sacrificial love of his father, the young man was given new life. We, too, have fallen headlong from the mountain of righteousness and lie broken and wounded by sin, with our life fast ebbing away. But if we turn to the Master, he freely gives us his pure blood so that we might be saved from death and regain life. Indeed, he came to us for this very purpose.”
