Since there is no necessity in God or for God, His creative acts are not necessary. Still, He does create angelic and human persons. However, it is fairly clear that many of those God has created have turned their backs on Him. He knew this would happen. Since He does not “have to” create, one might well ask: Why does He bother?
God is Power, Wisdom, and Love. Human beings possessing these attributes give them to others. Power is meaningless if it is not exercised. For example, what benefit does bodily strength have if it is never used in work or in play? Wisdom is useless if it is not shared. For instance, why would a scholar spend years studying if he never intends to transmit his knowledge either in teaching or in writing? Love is a self-gift of one person to at least one other person. Thus, how can one love without giving oneself to another? As human persons, we share our strength, our wisdom, and our love. God is like us. As Power, Wisdom, and Love, God seeks to share Himself. He does not create out of any necessity, but rather out of a burning desire to give His power, His wisdom, and His love to others.
