Are you at peace? You don't want to get to your death bed, and find there is no rest, no peace. Is there rest, is there peace between you and God? Or is your life not at rest? Jesus says, "Come!" and there is no one more qualified to come and preach peace. He's the very one that made peace between God and man. He took all that hostility, He took all the severe punishment for all those sins; so that we would have peace with God.
