The love of the world can not be expunged by a mere demonstration of the world's worthlessness. But may it not be supplanted by the love of that which is more worthy than itself? The heart can not be prevailed upon to part with the world, by a simple act of resignation. But may not the heart be prevailed upon to admit into its preference another, who shall subordinate the world, and bring it down from its wonted ascendency? If the throne which is placed there must have an occupier, and the tyrant that now reigns has occupied it wrongfully, he may not leave a bosom which would rather detain him than be left in desolation. But may he not give way to the lawful Sovereign, appearing with every charm that can secure His willing admittance, and taking unto Himself His great power to subdue the moral nature of man, and to reign over it? In a word, if the way to disengage the heart from the positive love of one great and ascendant object is to fasten it in positive love to another, then it is not by exposing the worthlessness of the former, but by addressing to the mental eye the worth and excellence of the latter, that all old things are to be done away, and all things are to become new. This, we trust, will explain the operation of that charm which accompanies the effectual preaching of the gospel. The love of God, and the love of the world, are two affections, not merely in a state of rivalship, but in a state of enmity, and that so irreconcilable that they can not dwell together in the same bosom. We have already affirmed how impossible it were for the heart, by any innate elasticity of its own, to cast the world away from it, and thus reduce itself to a wilderness. The heart is not so constituted, and the only way to dispossess it of an old affection is by the expulsive power of a new one. Nothing can exceed the magnitude of the required change in a man's character--when bidden, as he is in the New Testament, to love not the world; no, nor any of the things that are in the world--for this so comprehends all that is dear to him in existence as to be equivalent to a command of self-annihilation. But the same revelation which dictates so mighty an obedience places within our reach as mighty an instrument of obedience. It brings for admittance, to the very door of our heart, an affection which, once seated upon its throne, will either subordinate every previous inmate, or bid it away. Beside the world it places before the eye of the mind Him who made the world, and with this peculiarity, which is all its own--that in the gospel do we so behold God as that we may love God. It is there, and there only, where God stands revealed as an object of confidence to sinners--and where our desire after Him is not chilled into apathy by that barrier of human guilt which intercepts every approach that is not made to Him through the appointed Mediator. It is the bringing in of this better hope, whereby we draw nigh unto God--and
