“He will judge between the nations and will settle disputes for many peoples. They will beat their swords into plowshares and their spears into pruning hooks. Nation will not take up sword against nation, nor will they train for war anymore.” (Isaiah 2:4)
The same passage is repeated nearly verbatim in Micah 4:3. The idea is that people stop making weapons and fighting each other and instead grow food and feed each other. The warriors become gardeners and all live at peace. It’s a vision of repentance and a return to God’s way of love, which is the purpose of this ministry.
