To bridge then the abyss between human and divine, it is necessary to find within the created nature of man some kind oi ledge, or base, or some point d'appui, where the grace of God could alight, and there infuse life. Or, to vary the metaphor (and the use of metaphor is our only way of stating these truths), there must be within the creature a ground or soil in which God could plant a seed, an embryo of his own life of grace. In the first days of preaching the Gospel of Christ, his apostles made use of the metaphor of engrafting, a figure of speech as suggestive and accurate as human words could well be; and by this was intended the implanting of a new growth or life upon some different trunk, which was already in its own order alive.
