The story of Abraham and Isaac is undoubtedly one of the hardest passages to read in Scripture. In Sunday school we sing about “Father Abraham” and his many sons, but we often sidestep this gruesome chapter. It’s uncomfortable and disturbing, bringing to light moral, ethical, and theological questions that have been debated for centuries. From Martin Luther, who praised Abraham’s “blind faith,” to Immanuel Kant, who concluded that God could not have actually asked Abraham to sacrifice his son—the list of scholars and theologians who have wrestled with this story and its meaning is long.

It is wise to approach Genesis 22 with a self-awareness of our finite understanding of God’s mysterious ways. We ought to approach it with a view of the whole of Scripture, seeing it as a single story that teaches us something about God but also as one that fits into the much larger narrative of the gospel, teaching us about sacrifice, substitution, and provision.

We can take heart in verse 1, which tells us that God set out to “test” Abraham. And Abraham rose to the occasion in faith; throughout the story, Abraham believes that God will provide (v.8).

Abraham knew he could trust God, who had promised him land (Genesis 12:1–9), an heir despite his old age and his wife’s barrenness (ch.17), and offspring more numerous than the stars (ch.15). Abraham’s faith was not blind, but it was rooted in seeing God’s faithfulness to him. And so when God said to take Isaac and bind him for sacrifice—when it seemed that by following God’s instructions, God’s other promises would be void—Abraham acted in faith, saying “the LORD will provide” (22:8).

And again, God was faithful to Abraham. He kept His original promises by sending a ram to die in Isaac’s place, allowing the lineage to continue. Abraham named the mountain they were on “The LORD Will Provide,” and Abraham lived the rest of his days in faith that God would continue to provide.

Later in Scripture, in the book of Leviticus, when God demanded sacrifices from His people, they were not tests like Abraham’s. Rather, the Levitical sacrifices were for atonement—for the covering of sin. The Israelites made those sacrifices with animals, but they were always temporary. Year after year, on the day of atonement, priests would offer the substitutionary death of animals to cover the sins of the people (Leviticus 16). Finally, God sent one perfect, final substitute: Himself. “God sent his one and only Son into the world so that we might live through him” (1 John 4:9).

When we pray “O come, perfect substitute,” we cry out with faith like Abraham’s, rooted in the steadfast faithfulness of our God through the ages. The God who provided a ram for Isaac, who provided a system of animal sacrifices for His people to draw near to Him, has provided a perfect sacrifice, once and for all, for everyone who would believe in His Son, Jesus.

O come, perfect substitute, Jesus our King!

    I want to strive to be as faithful and as obedient as Abraham. Thank you God for the new covenant of love through your son Jesus Christ!

    I have read this passage before and every time it reminds me of how much control I think I have that I really need to let go of. Faith is strength. God is in control. He will provide. His will will be done.

    I just finished going through Angie Smith’s Seamless Study. From a higher view I have a much better understanding now of the Old Testament and the connection and deeper meaning of the Nee Testament in relation to it. It really helped me better understand significance of the veil being torn in two for example and all the laws and rules the people followed starting in Genesis.

    It’s so scary to what God asked of Abraham to sacrifice his son. The son that he has been waiting years for!!

    But at the same time it is beyond imaginable how much FAITH ABRAHAM HAD!!!!! That no Matter what… the Lord will provide!!!!
    May we all continue to strive for FAITHFUL SPIRITS LIKE ABRAHAM!!!!!

  5. Carly Davis says:

    I love the faith in verses 5 and 8!! He said “We will worship and then WE will come back to you,” and “The Lord will provide the lamb.” He knew somehow God would keep his promises, I think even if it meant bringing Isaac back from the dead Abraham had faith!

    Love the message! God knows and loves us so much

    I want to and pray that I become as obedient as Abraham was, God told him to sacrifice his son as a burnt offering and not once did Abraham question God or ask why or any of that Abraham put all his trust in God and knew He would provide a way. I also want to be like Isaac he never questioned his fathers faith or questioned why he was doing things God asked of Abraham Isaac trusted his father through it all and was never steered in the wrong direction.

    I heard this from Angie Smith at a conference a couple of years ago and it has stuck with me:
    The first two questions in the Bible are:
    1. Satan – Are you sure you can trust God? Genesis 3:1
    2. God – Where are you? Genesis 3:9

    God is looking at the posture of our hearts. God promised a lamb but provided a ram to Abraham.

    When you hear the enemy whisper “are you sure?” You say, “I am certain about the Lamb, but I am uncertain about the ram.”

    The answer to the next question, “where are you?” is, “Here I am, ready and willing.”

      I kept thinking of Angie’s talk on this passage while I was reading, but I couldn’t quite remember how she phrased it. Thanks for sharing! God’s perfect timing, per usual.
