Abraham’s Great Act of Faith

“By faith Abraham, when he was tested, offered up Isaac, and he who had received the promises was in the act of offering up his only son, of whom it was said, ‘Through Isaac shall your offspring be named.’ He considered that God was able even to raise him from the dead, from which, figuratively speaking, he did receive him back” (Heb. 11:17–19).

Apart from Christ’s obedient sacrifice, probably the greatest act of faith in fear and trembling recorded in all of Scripture is the obedient response of Abraham when God commanded him to sacrifice his son Isaac. This occurred after God had given Abraham a promise of future generations through Isaac and after God had made him wait many years for the birth of Isaac. In the interim, Abraham had taken steps to make sure that this promise was fulfilled with the aid of his wife Sarah, who, regarding herself as barren, offered her handmaid Hagar as a surrogate mother so that Abraham could have a son in order to fulfill the promise. Hagar had a son named Ishmael—but he was not the son of promise. Finally, after more years of waiting, God opened the womb of Sarah, and in her old age and in her barrenness, she brought forth a son who was given the name Isaac (when told she would have a son, Sarah had laughed, and the name Isaac means “laughter” in the Hebrew language). All of Abraham’s hopes, his entire destiny, was wrapped up in this child.

Then God came to him and said, “Take your son, your only son Isaac, whom you love, and go to the land of Moriah, and offer him there as a burnt offering on one of the mountains of which I shall tell you” (Gen. 22:2). Abraham, in fear and trembling, set out on that three-day journey with Isaac. On the way, Isaac asked Abraham, “Behold, the fire and the wood, but where is the lamb for a burnt offering?” (v. 7). Abraham responded, “God will provide for himself the lamb” (v. 8). Keep reading
