Sermon for the Fifth Sunday after Pentecost, Year A (6-28-26)

There are some passages of scripture that seem to preach themselves. Our reading from Genesis is not one of them. The story of the sacrifice of Isaac has unsettled readers for centuries, and for good reason. It begins with a command that feels almost impossible to reconcile with the loving God we encounter elsewhere in scripture:

"Take your son, your only son Isaac, whom you love... and offer him there as a burnt offering."

The text itself lingers over the relationship, because Isaac is not simply a child. He's the very child whose birth came after decades of waiting. Isaac is not simply part of God's promise to Abraham; he is the promise — or at least the only visible sign of it.

Through Isaac, God has pledged a future. Through Isaac, God has promised descendants more numerous than the stars. Through Isaac, God has done impossible things. Which means that what is being placed on the altar is not simply a beloved child. Isaac embodies Abraham's understanding of how God keeps God's promises.

That may not remove the difficulty of the story, but it helps us see more fully what's at stake.

It also helps to remember that Abraham lived in a world very different from our own. We tend to hear this story as uniquely shocking, but ancient hearers might very well have been more startled by different parts. In many ancient cultures sacrifice was woven deeply into religious life, and there is evidence that some neighboring peoples — including the Phoenicians and later the Carthaginians — practiced child sacrifice in moments of dire crisis.

The logic was straightforward: if the gods favor was doled out in relation to the preciousness of the sacrifice, then perhaps offering what was most precious would secure their highest favor. A devastating option employed when there was seemingly no other option for the group's survival. So, against that backdrop, today's story begins in a way that would have felt familiar enough to many ancient readers. In fact, what likely would have seemed surprising wouldn't have been the command to sacrifice Isaac, but the interruption of the act itself.

Abraham reaches the mountain. The altar is built, and the wood is arranged. The knife is raised. And at precisely the moment when the surrounding cultures would have expected the sacrifice to proceed, that is when God intervenes. A ram is provided, and Isaac goes home alive.

For the ancient people of Israel, this story was not just about Abraham's obedience. It was also — and I would argue more so — about God's character. A declaration that the God of Abraham was not like the gods worshiped by the nations.

In other words, the central question of this story may not be, "How much faith does Abraham have?" The deeper question may be, "What kind of God is this?" That question permeates our bible stories, and as it does we see God's people learning to distinguish the true and present living God from the gods they imagine God to be.

We're often tempted to imagine a God who demands certainty before offering blessing. Or who withholds love until we prove ourselves worthy; whose favor must somehow be earned. Or worst of all, a God who abandons us when life becomes difficult.

Yet the God revealed in this story is different.

Abraham scales the sacrificial mountain believing that everything depends on him: his actions, his obedience, his sacrifice. But he descends having learned that the mechanics of the promise rests with God. And so, he names the place in a way that he will be remember that lesson: Yahweh Yireh - "The Lord will provide."

It's a curious name when you think about it. Abraham doesn't call it "The Lord will test" or "The Lord will demand." He names it after what he has learned about God's character in the midst of the ordeal. "The Lord will provide."

The challenge, of course, is that God's provision rarely arrives in the form we would prefer. We typically like provision to include certainty; to be folded into an obvious solution, or a detailed explanation of how everything is going to work out.

Yet Abraham receives none of those things. He does not see the ram before beginning the journey. He does not receive an explanation halfway up the mountain. The provision becomes visible only when he reaches the limits of his own understanding and ability.

And the same pattern appears throughout scripture. The Israelites encounter manna only after entering the wilderness. The disciples learn the abundance of Christ only after discovering that what they have is not enough. Again and again, God's people are brought to the uncomfortable realization that the future rests not in their own hands, but in God's.

Most of us know something about that experience. We know what it's like to face uncertainty about our health, our families, our future, or the future of those we love. We know what it feels like to stand in situations where we cannot imagine how God's promises can possibly be fulfilled.

Sometimes God's provision arrives not as an escape from difficulty, but as the grace to endure it. It arrives through a community that refuses to let us walk alone. It arrives through strength we didn't know we possessed. It arrives through ordinary acts of kindness and care that remind us that God has not abandoned us. And sometimes, yes, it arrives meeting the exact shape of our need in ways we simply cannot chalk up to coincidence.

That may be one way of hearing Jesus' words in today's gospel. Jesus speaks of welcoming one another, receiving one another, offering even a cup of cold water in his name. Those actions seem remarkably ordinary. Yet they reveal something important. God's provision often takes shape through human hands. Through neighbors. Through friends. Through the simple faithfulness of people who embody God's love for one another.

For Christians, the question raised by Genesis 22 ultimately leads us to Christ. The church has long noticed the echoes between Isaac and Jesus: the beloved son, the journey toward sacrifice, the wood carried up the mountain. Yet, the deepest connection lies elsewhere.

The God revealed in Jesus is the same God Abraham encountered—the God whose final word is not destruction, but provision. And at the cross, we see that provision carried further than Abraham could ever have imagined. God does not remain distant from human suffering, demanding sacrifice from afar. God enters into human suffering and bears it. The God who provided a ram for Abraham ultimately provides God's very self for the life of the world.   

And so, the story ends where Abraham leaves it: not with every question answered, but with a clear confession of faith. The Lord will provide. Not because life is easy, and not because the future is always clear. But because the God we meet on this mountain is not a God who consumes life. Rather a God who gives it. And who provides.

Amen.
