Can God intervene in this world, and if so, to what extent? If God intervenes, can we initiate such intervention by prayer? And if God can intervene, why is evil so persistent? Taking up such practical but profound questions, a coauthor of the much-discussed The Openness of God here offers a probing philosophical examination of freewill theism. This controversial view argues that the God of Christianity desires "responsive relationship" with his creatures. It rejects process theology, but calls for a reassessment of such classical doctrines as God's immutability, impassibility and foreknowledge. David Basinger here especially considers divine omniscience, theodicy and petitionary prayer in freewill perspective. His careful and precise argument contributes to a growing and important discussion within orthodox Christian circles.
