'Peace' in the Bible

Grace be to you and peace from God our Father, and from the Lord Jesus Christ.

But all things are of God, who has made us at peace with himself through Christ, and has given to us the work of making peace;

That is, that God was in Christ making peace between the world and himself, not putting their sins to their account, and having given to us the preaching of this news of peace.

So we are the representatives of Christ, as if God was making a request to you through us: we make our request to you, in the name of Christ, be at peace with God.

Finally, brethren, farewell. Be perfect, be of good comfort, be of one mind, live in peace; and the God of love and peace shall be with you.
