Event: The Fifth Sunday in Lent, Year C
Isaiah 43:16-21 (EHV)
This is what the LORD says,
who makes a road through the sea
and a path through mighty waters,
17who brings out the chariot and the horses,
the army and the strong warrior.
They will all lie down together.
They will not get up.
They are extinguished.
Like a wick they go out.
18Do not remember the former things.
Do not keep thinking about ancient things.
19Watch, I am about to do a new thing.
Now it will spring up. Don’t you know about it?
Indeed I will make a road in the wilderness.
In the wasteland I will make rivers.
20The wild animals, the jackals and ostriches, will honor me,
because I am providing water in the wilderness,
rivers in a parched wasteland,
to provide water for my chosen people to drink.
21This people that I formed for myself will declare my praise.
Look at What God Is Doing!
“Hey, watch this!” Depending on who is saying those words, you might have different expectations of what you’ll see. If it’s a very young child, it might be some new-and-a-big-deal-to-them type of physical maneuver or something new they learned that aligns with their growth and development. If someone has been studying sleight-of-hand illusions, you might see something that seems impossible at first glance. And if it’s a layman working on the plumbing at the kitchen sink, perhaps you’ll see a great success or a wild failure as the water gets turned on. But in any case, you want to watch and see, either to encourage, be amazed, or know if you need to get the mop.
But what about when God says to you, “Hey, watch this!”? Depending on what you know about him or how you sense your relationship's health with him, you might be filled with excitement or dread. But certainly, if God is saying that we should look and watch, then we do well to look and watch. And that is exactly what God says to us today in our reading from Isaiah. He calls on us to bear witness to what he is doing because it is important—eternally important for us and for all people.
Our brief reading begins with all sorts of allusions to the exodus when God rescued his people from their slavery in Egypt. The exodus took place around 700 years before Isaiah’s ministry—roughly three times the length of the United States’ existence. So this happened a long time before this, but in Isaiah’s day, it ranked as the high water mark of God’s saving work. God is described as a God who saves with this language: who makes a road through the sea and a path through mighty waters, who brings out the chariot and the horses, the army and the strong warrior. They will all lie down together. They will not get up. They are extinguished. Like a wick they go out. This is a direct reference to the parting of the Red Sea, which enabled the Israelites to cross over the seabed on dry ground, and then the crash of the waters on the Egyptian army as they tried to pursue God’s people, to their destruction.
In other words, “Do you want to know who God is? Look at the exodus!” Notably, the all-capital-letters-LORD, God’s name of covenant love, is used here. He promised that he would rescue his people from their slavery, and through many miracles, plagues, and even the naturally-impossible parting of a large body of water, God did just that.
What does God say about this event by which glorified him as the saving God? He says, “Forget all of that because it’s going to seem like nothing compared to what I’m going to do. Do not remember the former things. Do not keep thinking about ancient things. Watch, I am about to do a new thing. Now it will spring up. Don’t you know about it?” As we said, when God says, “Hey, watch this!” we do well to pay attention! God is calling to us to look because, to paraphrase, “Ya’ ain’t seen nothing yet.”
So, what does God want us to see? “Indeed I will make a road in the wilderness. In the wasteland I will make rivers. The wild animals, the jackals and ostriches, will honor me, because I am providing water in the wilderness, rivers in a parched wasteland, to provide water for my chosen people to drink.” While roads running through barren lands and rivers appearing in the desert are interesting—useful, even—what is it about this work that makes it superior to the miraculous exodus? What about this could be considered “new,” from the God who created the world—desert and river alike—from nothing? Well, if he were talking about actual rivers in actual deserts, then, nothing. But this is something more, something bigger, something new.
God aims to bring relief and help to those in desperate need. He’s getting ready to bring life to something dead, like springs of water would be in the middle of a barren wasteland. He’s getting ready to do this new thing to save people from eternal death with eternal life.
This is not new because it was a secret no one had ever heard. Quite the contrary. God had been clear from the beginning that a champion was coming to rescue people from their sins. Elsewhere in his book, God gives remarkably clear prophecies and promises about this Savior through Isaiah. No, but it’s new because it’s something that had never been done before and would never happen again.
The life-giving water of forgiveness would be given to God’s people to drink, and there would be enough for every person who ever lived to satisfy their spiritual thirst. This the work that Jesus will embark on, to make the one-time, one-and-done payment for sins. This new thing would be God himself taking on our humanity, living among us, allowing himself to be sacrificed for us, and in doing so, paying for every misdeed and sin you and I have ever committed.
The reminder of the exodus ahead of the announcement of this imminent new thing is very helpful. If there was ever a time that it seemed like God’s promises couldn’t happen as he said they would, it would be the exodus. As his people left Egypt, the pharaoh had a change of heart and wanted his slaves back. He pursued the people with his army—armed warriors against a nation of just-released slaves. They had no weapons or defense force to speak of; they had no combat training. This group of two million people could probably have done very little to make a stand against the Egyptian military.
Add to that the location where the army caught up with the Israelites, at the shore of the Red Sea. They were hemmed in on all sides—water to one, the enemy army to the other. Rock, hard place. And so, what does God do? Whatever is necessary to keep his promises. The waters of the Sea part, the pillar of fire and cloud stands between his people and the Egyptians, and they cross over to safety and freedom, unscathed.
Nothing stands in God’s way when he’s made a promise. But I wonder how often we feel or think something is getting in God’s way regarding forgiveness. Perhaps the guilt we feel over sin—that conscience that won’t stop crying out about the condemnation it expects to face—makes it seem like this sin can never be dealt with, that we are doomed to perish in hell because we know that it is the just punishment for our sins.
Or maybe something else gets in the way; maybe we are in the way. Maybe our own lack of appreciation for what God has promised and done, our distractions and lack of focus on these immeasurably important eternal matters, or our general apathy with God’s work for us lead us to wander away from God with little regard for what that will mean for us eternally.
My dear brothers and sisters, look at what God is doing! Don’t let this pass you by, uncaring. Don’t look at it as if it is ineffectual to save you. This new thing in Jesus is God’s full and free forgiveness for you! You were parched, dying of thirst under the brutal sun and scorching winds of your sin, destined to eternal death in hell. And here God comes with this new thing, with himself in human flesh, to take your place. He gives you to drink from the cool waters of his love and his forgiveness. And this drink does not fail to revive. Nothing will prevent God’s mission to save, not Pharaoh and his army, not the depths of the Red Sea, not the multitude and severity of your sin or mine. Here, in this new thing, they are gone. Here, we have life instead of death, now and for eternity.
Over these next few weeks, in our worship on Wednesday evenings and Sunday mornings, and especially during the run of Maundy Thursday, Good Friday, and Easter, we’ll see this new thing spring up. God promised the sacrifice of Jesus, and from it comes forgiveness that cannot and will not fail. The new thing that God promised is done. Your sins are forgiven. You have eternal life and perfect peace with your God as your certain possession.
In the days ahead, let us look and watch together as this new thing unfurls God’s love for us in Gethsemane, in the sham trials, at the cross, and even at his burial site. Amen.
