From his correspondence with Roger Olsen:
I think I would not be called an open theist by any thoughtful person who knows what I write and say. The points which strike some people as ‘open’ might be these. I believe that God does modify his actions in response to human beings on some occasions: does what he was not going to do or does not do what he was going to do. And I do not think he has to know every detail of created reality to bring it out where he wants it. But there isn’t anything He needs or wants to know that he does not know. The picture of God as a great, unblinking, cosmic stare is a projection upon him of how some people try to deal with control from a human point of view. But he has resources for achieving his purposes that no human being has, and he doesn’t have to be mean or immediately on top of every detail of existence in order to run the universe. He does have considerable help and no need to micro-manage everything. If I leave some things to my helpers, as an administrator, that does not mean that I close off part of the future to my sight. But if I did not limit myself in terms of what I could know, and what I would do, it would soon ruin the operation. Limiting myself (‘holding back’) is not the same as ‘closing it off.’ Omniscience refers to God’s power to know absolutely everything. That I firmly accept. But I believe he does, by his choice, not know everything he could know—without it in any way defeating his purposes—and I also believe that human interaction with him modifies what he does or does not do in the details of individual and group life.
