Knowing God Will Change Us--December 12, 2025
"They will not hurt or destroy on all my holy mountain,
for the earth will be full of the knowledge of the Lord
as the waters cover the sea.
On that day the root of Jesse shall stand as a signal to the peoples;
the nations shall inquire of him, and his dwelling shall be glorious." (Isaiah 11:9-10)
When we know God fully, we will no longer need to hurt each other.
When we truly understand the character of God, we will no longer seek to destroy one another.
When we dare to see the world from God's perspective, all peoples and all nations will be able to live together, drawn together by God's chosen one, who comes from the old family line of Jesse, not merely coexisting, but in community.
This is really mind-blowing stuff if you think about it. These words, which conclude the passage from Isaiah that many of us heard this past Sunday in worship, give us one more glimpse of that "peaceable kingdom" we've been exploring over the last several days. Earlier, Isaiah had pictured all nations streaming to the mountain of God--to the very Temple in Jerusalem!--to be taught by God. Then we heard the prophet describing a new creation where creatures themselves are changed so that former enemies are reconciled and can live safely and in peace with one another: wolves and lambs, cows and bears, leopards and kids, all together and none afraid.
And to hear Isaiah tell it, all of that change--which is pretty radical, to be honest--is made possible by knowing God more deeply. The more fully we know God--not just facts "about" God, but to know the heart of God's character--the more completely we will be led away from wanting or needing to hurt one another. The more truly we know God's ways, the less we will be driven to cause harm, or to justify hurting others in the name of getting what we want. Isaiah seems to think that if we believe it is acceptable to hurt, destroy, or regard someone else as "less than," it is a sign that we don't really know God. From the prophet's perspective, all nations are welcome and none can be dismissed as disposable, as trash, or as garbage. Isaiah says that kind of mutual care is what happens when "the earth is full of the knowledge of the Lord."
All too often, we treat God as our private possession who is there to take OUR side against THEIR side. We tell ourselves that WE won't be hurt or destroyed if God is on our side, but that God is here to be the heavy who can smite, blast, and blow up whomever we decide is "unrighteous" or "ungodly." That's the thinking being used by "religious" voices in Russia trying to justify its invasion of Ukraine, and it's the same thinking that has been used by competing groups in Israel and Palestine to attempt to justify killing and bombing each other, and it's very tempting to do the same in our own setting. We have a very, VERY hard time resisting the temptation of believing that God is on MY side, and therefore is opposed to YOUR side. We have a very hard time considering that God might not be just MINE or seeking MY safety, but the well-being and life of all. But that's precisely what Isaiah wants us to see.
From Isaiah's standpoint, the more clearly we understand who God is and what matters to God, the more we will commit to caring for one another, protecting one another from harm, and refusing to hurt one another. And Isaiah's repeated reference here to "the peoples" and "the nations" makes it clear that he doesn't just have his own country or clan in mind. We are not only called to refrain from harming our own little groups, but we are called to seek the well-being of all people. As Isaiah sees it, the more truly we know God, the less we will be able to say, "Me and My Group First," and the more we will be committed to the good of all. That's because Isaiah is convinced that God's own heart is committed to the good of all. For him, then, it only makes sense to say that no one will hurt or destroy because the earth will be full of the knowledge of the Lord.
Today, how can we deepen our knowledge of God--and are we prepared to let that deeper understanding change our way of relating to other people? Are we willing to let our study of the Bible change our perspective of our neighbors? Are will willing to allow that the more we learn, pray, and contemplate the character of God, the more we open ourselves to a new love of others, including others from backgrounds and stories that are very different from our own?
Isaiah warns us that we cannot reduce our knowledge of God to merely a matter of facts to be memorized and filed away in our brains; knowing God will change us. And in particular, knowing God more deeply will make of us people who love deeply, who seek to preserve the lives of others, who honor and uplift the worth of all peoples and all nations, and who do not hurt or destroy others. Dare we let our relationship to God change us that way?
Lord God, help us to know you more deeply, and allow that knowledge to shape us more fully in your likeness.
