Genesis 22:12

“And he said, lay not thine hand upon the lad, etc.] Which he was just going to stretch out, with his knife in it, to slay him; and though the Lord had bid him take his son, and offer him for a burnt offering, to try his faith, fear, love, and obedience, yet he meant not that he should actually slay him, but would prevent it when it came to the crisis; for he approves not of, nor delights in human sacrifices; and that this might not be dawn into an example, it was prevented; though the Gentiles, under the influence of Satan, in imitation of this, have practised it: neither do thou anything unto him; by lacerating his flesh, letting out any of his blood, or wounding him ever so slightly in any…”

“22:12 Now God knew that Abraham would hold nothing back from him, that he did truly fear God. To fear the Lord means to reverence him as sovereign, trust him implicitly, and obey him without protest. The sacrifice that pleases God is a heart broken of self-will, surrendered to God (Pss 40:6-8; 51:17) and offering its best to God. • You have not withheld: Cp. Rom 8:32, which uses the same verb (“spare”) as the Greek Old Testament uses here. If God gave us his dearest possession, he will surely provide all things for us.”
