10:6-9 Many who hear the word of Christ, do not understand it, because they will not. But we shall find one scripture expounding another, and the blessed Spirit making known the blessed Jesus.

Also, we have precious promises to those that observe this direction. Christ has all that care of his church, and every believer, which a good shepherd has of his flock; and he expects the church, and every believer, to wait on him, and to keep in his pasture.
