THE SAINTS' KNOWLEDGE OF CHRIST'S LOVE: or, the Unsearchable Riches of Christ, Eph 3:18, 19. The extent implied in the words breadth, length, depth, and height; as far beyond all other breadths, lengths, depths, and heights, as God is infinitely beyond all creatures. Some degrees of this love may be known; he the happier who ascends the highest on Jacob's ladder; but the full extent can only be known in heaven.
