Genesis 22:12Meaning & Commentary from the Church Fathers

“Do not raise your hand,” He instructs, “against the boy. I have not commanded that this act be fulfilled, nor do I wish for you to sacrifice your son, but rather to demonstrate your obedience to all. Therefore, do nothing to him; I am pleased with your willingness, and for this I shall honor and exalt you. “Now I know that you fear God.” Consider the grace in these words. What does this mean? Did the Lord not recognize the righteousness of His servant before this moment, only acknowledging it now?

When the child questioned his father, saying, "The fire and the wood are here, but where is the lamb for the burnt offering?" the father replied, "God will provide for Himself a lamb for the burnt offering, my son" (Genesis 22:7-8). Upon constructing the altar dedicated to God, he placed the wood upon it and, after binding the boy, lifted the knife. However, the voice of the angel stopped him, instructing him not to harm the child, for God had already observed his righteous intent. Then the man of faith, upon seeing a ram caught by its horns in the thicket of the Shebek garden, offered that as a sacrifice in place of his son. Thus, Isaac was spared from death and anguish, while the ram, appointed by God, was offered on the altar.

God does not temporarily gain knowledge of anything that He was not already aware of; however, He speaks to Abraham, saying, “Now have I made it known that you fear God,” which conveys nothing more than this: “Now I have made it known” that you possess reverence for God. Through such statements, when we refer to matters not inherent to God as if they were part of Him, we indicate that God transforms them into something representative of us; yet this applies only to that which is commendable and in accordance with what is allowed by Scripture. We must refrain from speaking thoughtlessly about God in ways that we do not find recorded in His holy writings.

To prevent Abraham from assuming that his offering was rejected due to any imperfection, God assured him, "Behold, you have demonstrated your reverence before Me, and through Him who is most gracious to you, your love for the Lord of all has been unveiled." Thus, Abraham was esteemed not only because he had already sacrificed his son in his heart, despite not having done so physically, but also because he held firm in his belief that his son would indeed rise after death and return with him, confident in the truth of the promise: "As in Isaac shall your seed be called" (Gen. 21:12). The heavenly beings, including angels, principalities, powers, thrones, dominions, and all the heavenly host were left in awe; the heavens, sun, moon, and stars were struck by this remarkable event.

Driven by the utmost devotion, Abraham was prepared to present his son as a burnt offering in obedience to God’s command. Acting with such urgency that he seemed to abandon his natural instincts, he raised the knife, fearing that any delay would diminish his offering. However, when he received the command not to harm his son, he joyfully sheathed the knife and, filled with even greater piety than before, swiftly turned to offer a ram instead as a sacrifice.

It is beyond dispute that God's understanding is revealed at the appointed time rather than being subject to change, for concerning what God knows, it is more accurate to speak of the right moment for its revelation than its acquisition. This is illustrated by the words addressed to Abraham: "Thou shalt not lift up thy hand against the young man, nor do anything over him: for now I know that thou fearest the Lord thy God, and hast not spared thy son, thy beloved, for Me." Here, God’s awareness is described in a current context, yet such knowledge implies prior unawareness. However, it is not unusual for God to have had prior unknowing regarding Abraham's fidelity, as it is written, "Abram believed God, and it was accounted to him for righteousness" (Gen. 15:6; Gal. 3:6).

What is the significance of Isaac being taken to the sacrifice, placed upon the altar, and yet remaining alive? It symbolizes that our Savior, who was brought to the crucifixion, gave His life for us in the flesh, while He continued to exist eternally in His divinity.

He spoke to Abraham, declaring, "Now I know that you fear God," suggesting, "Now I have revealed to humanity, who were unaware, what I have always confidently known: that you truly revere God."

When the Lord spoke to Abraham, saying, “Now I know that you fear God” (Genesis 22:12), He indicated a profound reverence that stems from love. It raises the question of why He would declare, “Now I know,” considering the many acts of obedience that Abraham had already performed, such as leaving behind everything to journey to a foreign land inhabited by idolaters, where there was no indication of the worship of the true God. Moreover, God subjected him to an immense trial—the sacrifice of his son—and only then did He proclaim, “Now I know that you fear God.” This highlights a special kind of reverential fear found in the saints, who do not follow God's will out of dread of punishment or the hope of reward but out of love.

Although Abraham's son was prepared to offer himself to God, Abraham bound him to prevent any hesitation in defending himself. He then placed him on the altar and raised the knife to sacrifice his son. Observing this from heaven, the Lord, through His angel, stopped Abraham's hand, saying, "Abraham, Abraham, do not lay your hand on the boy, and do nothing to him. Now I know that you fear God, since you have not withheld your only son from me" (Gen. 22:12). In this instance, Chrysostom conveys God's message to Abraham: "I did not command this act, nor do I desire your son's death; rather, I wish for your obedience to be evident to all. Therefore, do not harm him. Your willingness is enough for me, and for this alone I honor and glorify you."

Now I understand, etc. The understanding ascribed to God in Scripture does not imply any prior ignorance on His part. Therefore, David declares, "Test me, O God, and know my heart" (Psalms 139:23), which follows his acknowledgment of God’s omniscience and omnipresence. As God, in the absolute purity of His being, fully comprehends the only good and expels all evil from His perfectly good will and all-inclusive mind (Luke 13:27), when He refines humanity through profound and vigorous trials, ascends them, grounds them in righteousness, and brings them into communion with Himself, it can rightly be said that He knows humanity. Thus, He recognized Moses by name (Ex. 33:17), and He was aware of Abraham during the testing of his son.

"Do not lay your hand upon the boy... him that": stay the motion of your hand poised over the sacrificial knife. My command regarding the offering of Isaac was not intended for literal execution. I do not wish for you to take the young man's life, but rather for your obedience to be made manifest. I witness your willingness and your intent to offer your son out of love for Me, and with this sentiment alone, I am fulfilled; do not strike down one whom you have already sacrificed in thought and intention. - "Now knowest thou that thou fearest God" The phrase, “now knowest thou,” is a human expression. He who is all-knowing and who discerns hearts and spirits was aware of what Abraham could accomplish beforehand.
