If we do not know who God is and how He thinks and what He does, we have no grounds for joy, no reason to celebrate, no basis for finding satisfaction in God. Delight in God cannot occur in an intellectual vacuum. Our joy is the fruit of what we know and believe to be true of God. Emotional heat (i.e., joy, delight, gladness of heart) apart from intellectual light (knowledge of God) is useless. Worse still, it is dangerous, for it inevitably leads to fanaticism and idolatry.
