Of all of the theological issues that have arisen in the last couple of decades, the matter of what God is like has to be one of the most crucial. As A. W. Tozer has written, "[T]he most portentous fact about any man is...what he in his deep heart conceives God to be like. We tend by a secret law of the soul to move toward our mental image of God" (A. W. Tozer, The Knowledge of the Holy, 7).
Of course, all orthodox Christians agree that God is a Trinity, three persons in one essence. But just how powerful is this God? Does He control all things, even the details of life? Does He even know all things past, present, and future? Some evangelicals seem to be unsure.
Other evangelical theologians are passionately arguing the negative: God is neither in full control of the world, nor does He even know the details of the future. According to these Open Theists,
God knows a great deal about what will happen....he knows everything that could happen and what he can do in response to each eventuality. And he knows the ultimate outcome to which he is guiding the course of history. All that God does not know is the content of future free decisions, and this is because decisions are not there to know until they occur. (Richard Rice, The Grace of God and the Will of Man, ed. Clark Pinnock, 134)
