Christians throughout history have been strengthened by their confidence that God knows everything about the future. However, open theism claims to offer a more biblical and a more practical alternative to traditional views of God s sovereignty and involvement in our lives. Bruce Ware carefully summarises and critiques this redefinition of the nature of God. He provides an excellent treatment of both classical and open theism, explores their implications and pinpoints the subtle ways in which open theism undermines our trust in God and lessens his glory.
