The question of personality does not turn upon mere extent or expansion of being, whether physically or even psychically considered, but rather upon the traits or characteristics of being. In considering the subject of God’s personality, it is a proper inquiry, whether he possesses intelligence which is cognizant of the fact of his own existence and power; whether he has the capability of knowing and affirming the fixed relation of himself, both in perception and action, to that interior law of rectitude which is also a part of his being; whether he possesses a volitional power correspondent to the powers of perception and the claims of moral obligation? It is in the answer to such questions as these, that we find the basis of personality considered as a fact or realization. And if the answer is in the affirmative, then God most evidently possesses all the requisites of personality, and stands forth before the universe, not merely as a blind and unintelligent principle of movement, but as a personal God, capable of intelligent design and action, endowed with responsibility both to himself and to all beings that are dependent on him, and entitled, in the case of those who are dependent, to obedience and homage.
