Theodoret of Cyrus: God's Will is Humankind's Salvation

He goes on to say the same thing a different way: He removes the first to let the second stand. By first he meant the sacrifice of brute beasts, by the second the rational one, offered by himself. By this will we have been sanctified through the offering of the body of Jesus Christ once and for all (v.10). He brought out clearly that God's will is the salvation of humankind. The Lord also said as much, "This is the will of my Father, that everyone who believes in me may not be lost but may have eternal life."
