In the new Theocracy, the true kingdom of God, the ancient symbol of the Divine presence will be forgotten in the realization of that presence. The institution of the New Covenant will be characterized by an immediate and personal knowledge of Iahvah in the hearts of all His people (xxxi. 31 _sq._). The small object in which past generations had loved to recognise the earthly throne of the God of Israel, will be replaced by Jerusalem itself, the Holy City, not merely of Judah, nor of Judah and Israel, but of the world. Thither will all the nations resort "to the name of Iahvah;" ceasing henceforth "to follow the hardness (or callousness) of their own evil heart." That the more degraded kinds of heathenism have a hardening effect upon the heart; and that the cruel and impure worships of Canaan especially tended to blunt the finer sensibilities, to enfeeble the natural instincts of humanity and justice, and to confuse the sense of right and wrong, is beyond question. Only a heart rendered callous by custom, and stubbornly deaf to the pleadings of natural pity, could find genuine pleasure in the merciless rites of the Molech-worship; and they who ceased to follow these inhuman superstitions, and sought light and guidance from the God of Israel, might well be said to have ceased "to walk after the hardness of their own evil heart."[24] The more repulsive features of heathenism chime in too well with the worst and most savage impulses of our nature; they exhibit too close a conformity with the suggestions and demands of selfish appetite; they humour and encourage the darkest passions far too directly and decidedly, to allow us to regard as plausible any theory of their origin and permanence which does not recognise in them at once a cause and an effect of human depravity (cf. Rom. i.).
