He, who has faith in himself and his fellow-men, exclusive of faith in God, or just in proportion as God is excluded, is known by a disposition to resort to human arts, and to rest strongly in human policy. And as a natural consequence of this, when the looks and the sayings of men are favorable, we find him cheered with increased hopes drawn from that source; but when the current of public sentiment sets in opposition, we see too clearly, that he is filled with despondency and dismay. Still, deceived by his own worldly spirit, he does not cease to place his hope where he placed it before. Even in his sorrows and disappointments, he casts upward no strong look of confidence towards God; or rather does not look towards him at all. But relying upon human strength, he continues to resort to those artifices which conciliate popular favor, while God is forgotten. And thus, deceived himself and deceived by others, he can find no true refreshment and strength of soul, because he applies to that “broken cistern, which can hold no water.”
On the other hand, the man, who has true and full faith in God, has no confidence, no faith in the creature, except as God’s instrument, as being under God’s direction, and as attended by God’s blessing. It is very proper, undoubtedly, and is entirely consistent with what has been said, to have faith in our fellow-men, and to have faith in ourselves, considered as God’s instruments, as reflecting God’s image, and as operating in the line of God’s providences; or in other words, to have faith in God in us. But it is not proper and it is not safe for us, as we have already seen, to have faith either in ourselves or in others, independently of God. The man, who has true faith in God, and who in having such faith is a true Christian, cannot do it.
