In 1893, the inventor of the machine gun was asked if his invention would make wars even more devastating. He replied that he believed they would make wars impossible. Many inventors and great scientists have said similar things over the years, only to discover that this was not the truth. Scientific progress has not slowed the beat of war, but has only made it far more deadly than it had ever been before.

Isaiah 2 gives us a foretaste of what will end war. The prophet paints a wonderful image of peace—people will beat their swords into plowshares, weapons will be repurposed into tools that grow and give life, and all nations will stream towards it to worship God (Isaiah 2:2,4). Then all people of the world will be united in worship of Him, and will finally lay their weapons down (Isaiah 2:3).

No better picture of these future events can be found than what took place in the early church. People who had previously experienced a contentious and even violent relationship with one another could see themselves as family: Jews, Gentiles, Samaritans, and Romans all unified, not because of science and progress but because they honored and worshiped the same God (Acts 10:34-38). Peter said, “In every nation he accepts those who fear him and do what is right” (Acts 10:35).

I know that I’m called to be a person of peace for Jesus is the Prince of Peace (Isaiah 9:6). But I often feel completely at a loss how to pursue that end—a world that is finally experiencing shalom. Isaiah reminds me that the way towards lasting and eternal peace is to worship God lovingly and to encourage others to do the same. Inviting others into a loving relationship with God is a step toward lasting peace on earth.
