God's Testimony in His Providences

But God has a testimony also or witness for himself in his providences; in other words, in all events which take place, especially when considered in their moral aspects and relations. The history of nations and individuals furnishes a series of facts, from which, if we could get it from no other source, may be deduced the general proposition, that all actions, which are not merely instinctive, have a moral character; and are attended with a moral retribution. We do not say, that the adjustment of reward and punishment to the moral merit and demerit of actions is entirely perfect in the present life; but it is so much so, as to leave no doubt of a moral government and a moral governor. It is true, that the vicious sometimes succeed in life, becoming rich and honored, while the virtuous suffer in poverty and contempt; but it does not follow from this, that the vicious are happy, or that the virtuous are miserable. The virtuous have an inward consolation, which more than compensates for outward adversities; and the vicious, with scarcely an exception, have inward sorrows, which are none the less deep and real for being concealed under the garb of outward prosperity. The history of man, therefore, including the history of nations as well as of individuals, utters its declarations loudly and impressively, in favor of God and of his government.

Holiness and Consent

We are not to forget, (and we are the more solicitous that we should not forget it, because great truths sometimes lie in the close vicinity of great errors,) that man is a moral being endued with the power of free choice; and that the divine presence cannot exist in him, as a principle of life, except with his own consent.

Moral life is a different thing from mere physical or instinctive life. There is a sense in which God is the life of everything. He is the life of the earth, the sky, the waters. He is the living principle of whatever the earth produces, — of the leaf, the flower, the plant, the tree. He is the life also, by means of  their various and wonderful instincts, of all lower animals. But he is their life, in some cases, without their knowing it at all, because they are not percipient existences; and in other cases, without their exhibiting any distinct recognition and knowledge, if it is possible that they have It. But it is not so with moral beings. God is and can be the life of such beings, only so far as he is so with their own consent. In the words of a modern English poet,

"Our wills are ours; we know not how;

Our  wills are ours, to make them  thine."

[Tennyson]

So that it is not more necessary that God should be our life, than it is that we should choose him to be so. If it be true that we cannot live without the life of God in the soul, it is also true that we cannot have that life without our own choice. And the reason is, that the principles of moral government, as it exists among beings who are subject to the supremacy of a divine government, require, without the exclusion of either, that there should be an harmonious action and union of the two in one. When God works within us with our own consent and in answer to our own prayer, then the human and divine may be said to be reconciled, because the work of God, by the harmonious adjustment of the two, becomes both the work of God and the work of the creature. So that it is true, in all cases of holiness actually experienced that the man lives and has a true life; while it is also true, and in a still higher sense, that God lives in him.
