2. The existence of God is the foundation of all religion. The whole building totters if the foundation be out of course: if we have not deliberate and right notions of it, we shall perform no worship, no service, yield no affection to him. If there be not a God, it is impossible there can be one, for eternity is essential to the notion of a God; so all religion would be vain, and unreasonable to pay homage to that which is not in being, nor can ever be. We must first believe that he is, and that he is what he declares himself to be, before we can seek him, adore him, and devote our affections to him.[13] We cannot pay God a due and regular homage, unless we understand him in his perfections, what he is; and we can pay him no homage at all, unless we believe that he is. 3. It is fit we should know why we believe, that our belief of a God may appear to be upon undeniable evidence, and that we may give a better reason for his existence, than that we have heard our {a27} parents and teachers tell us so, and our acquaintance think so. It is as much as to say there is no God, when we know not why we believe there is, and would not consider the arguments for his existence. 4. It is necessary to depress that secret atheism which is in the heart of every man by nature. Though every visible object which offers itself to our sense, presents a deity to our minds, and exhorts us to subscribe to the truth of it; yet there is a root of atheism springing up sometimes in wavering thoughts and foolish imaginations, inordinate actions, and secret wishes. Certain it is, that every man that doth not love God, denies God; now can he that disaffects him, and hath a slavish fear of him, wish his existence, and say to his own heart with any cheerfulness, there is a God, and make it his chief care to persuade himself of it? he would persuade himself there is no God, and stifle the seeds of it in his reason and conscience, that he might have the greatest liberty to entertain the allurements of the flesh. It is necessary to excite men to daily and actual considerations of God and his nature, which would be a bar to much of that wickedness which overflows in the lives of men. 5. Nor is it unuseful to those who effectually believe and love him;[14] for those who have had a converse with God, and felt his powerful influences in the secrets of their hearts, to take a prospect of those satisfactory accounts which reason gives of that God they adore and love; to see every creature justify them in their owning of him, and affections to him: indeed the evidences of a God striking upon the conscience of those who resolve to cleave to sin as their chiefest darling, will dash their pleasures with unwelcome mixtures.
