Genesis 22:16 By myself have I sworn, saith the Lord, for because thou hast done this thing, and hast not withheld thy son, thine only son. 17 That in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of the heaven, and as the sand which is upon the sea shore; and thy seed shall possess the gate of his enemies.
[Patriarchs & Prophets pp 153] Abraham's great act of faith stands like a pillar of light, illuminating the pathway of God's servants in all succeeding ages. Abraham did not seek to excuse himself from doing the will of God. During that three days’ journey he had sufficient time to reason, and to doubt God, if he was disposed to doubt. He might have reasoned that the slaying of his son would cause him to be looked upon as a murderer, a second Cain; that it would cause his teaching to be rejected and despised; and thus destroy his power to do good to his fellow men.
He might have pleaded that age should excuse him from obedience. But the patriarch did not take refuge in any of these excuses. Abraham was human; his passions and attachments were like ours; but he did not stop to question how the promise could be fulfilled if Isaac should be slain. He did not stay to reason with his aching heart. He knew that God is just and righteous in all His requirements, and he obeyed the command to the very letter.
“Abraham believed God, and it was imputed unto him for righteousness: and he was called the friend of God.” James 2:23. And Paul says, “They which are of faith, the same are the children of Abraham.” Galatians 3:7. But Abraham's faith was made manifest by his works. “Was not Abraham our father justified by works, when he had offered Isaac his son upon the altar? Seest thou how faith wrought with his works, and by works was faith made perfect?” James 2:21, 22.
Genesis 22:18 And in thy seed shall all the nations of the earth be blessed; because thou hast obeyed my voice. 19 So Abraham returned unto his young men, and they rose up and went together to Beersheba; and Abraham dwelt at Beersheba.
