Because he was faithful, you made an agreement to give his descendants the land of the Canaanites and Hittites, of the Amorites and Perizzites, and of the Jebusites and Girgashites. Now you have kept your promise, just as you always do.

What we mean is that God was in Christ, offering peace and forgiveness to the people of this world. And he has given us the work of sharing his message about peace.
