The endless, bottomless, boundless grace and compassion that is in him who is thus our husband, as he is the God of Zion. It is not the grace of a creature, nor all the grace that can possibly at once dwell in a created nature, that will serve our turn. We are too indigent to be suited with such a supply. There was a fulness of grace in the human nature of Christ,—he received not “the Spirit by measure,” John 3:34; a fulness like that of light in the sun, or of water in the sea (I speak not in respect of communication, but sufficiency); a fulness incomparably above the measure of angels: yet it was not properly an infinite fulness,—it was a created, and therefore a limited fulness. If it could be conceived as separated from the Deity, surely so many thirsty, guilty souls, as every day drink deep and large draughts of grace and mercy from him, would (if I may so speak) sink him to the very bottom; nay, it could afford no supply at all, but only in a moral way. But when the conduit of his humanity is inseparably united to the infinite, inexhaustible fountain of the Deity, who can look into the depths thereof? If, now, there be grace enough for sinners in an all-sufficient God, it is in Christ; and, indeed, in any other there cannot be enough.
