Few can carry up their hearts and minds to this height by faith, as to rest their souls in the love of the Father; they live below it, in the troublesome region of hopes and fears, storms and clouds. All here is serene and quiet. But how to attain to this pitch they know not. This is the will of God, that he may always be eyed as benign, kind, tender, loving, and unchangeable therein; and that peculiarly as the Father, as the great fountain and spring of all gracious communications and fruits of love. This is that which Christ came to reveal,—God as a Father, John 1:18; that name which he declares to those who are given him out of the world, John 17:6. And this is that which he effectually leads us to by himself, as he is the only way of going to God as a Father, John 14:5,6; that is, as love: and by doing so, gives us the rest which he promiseth; for the love of the Father is the only rest of the soul.
