God has made peace with you through Jesus. You didn't deserve it. You didn't earn it. But it’s true none-the-less. God made a two-way agreement with you where one side provided all of the collateral. And through it, he created reconciliation between you and God.
But it comes with future expectations. If you are at peace with God, then you are to help other people come to peace with God. You are Christ's ambassadors and you carry the ministry of reconciliation. So don't go starting wars. Don't go picking fights. Don't go needling opposition. Jesus followers don't contribute to war — we contribute to peace. Your job is to help people get right with God just like Jesus worked to get people right with God.
