If God rests by having his center in himself, man may rest by having his center in God; and the rest of man, having its supports in the Infinite Mind, may possess the same attributes as the rest of the Divinity. So that man derives his rest or peace of spirit from God, as he derives everything else from the same source. And just in proportion as we approach to quietness of spirit, founded on just principles, we approach in similitude to God. It is the quietist,— the man who moves unshaken in the sphere and path which God has marked out for him, unelated by joy, undepressed by sorrow, unallured by temptations, unterrified by adversities, — it is this man, bearing about always the divine calmness of his crucified Elder Brother, who is truly godlike. And, just so far as he is like God in character, he is like him in inward tranquility.
And it is such views as these which furnish the true explanation of the words of the Savior, which conveyed to his followers his parting legacy: “Peace I leave with you. My peace I give unto you."
