Matthew 5:9
Blessed are the peacemakers, for they will be called children of God.

This does not describe those who live in peace, but those who actually bring about peace, overcoming evil with good. One way we accomplish this is through spreading the gospel, because God has entrusted to us the ministry of reconciliation (2 Corinthians 5:18). In evangelism we make peace between man and the God whom they have rejected and offended.

The reward of peacemakers is that they are recognized as true children of God. They share His passion for peace and reconciliation, the breaking down of walls between people.

Application

Have plans to spread the gospel.
