The first book with a focus on free will theism with Christian and Muslim contributions on Divine Action. Muslims and Christians both believe in a personal God who cares for humans and is present in the life of religious believers. They address God in their petitionary prayers, give thanks to God for God's mercy and they long for God's justice. But is it still possible to give thanks to God for our lives if so many others around us seem to suffer without just cause? How can we rely on the power of intercession and divine involvement, if so many other urgent pleas to God appear to go unanswered? This book formulates Muslim and Christian responses to these questions from important contemporary scholars from both traditions - as Ebrahim Moosa, Muhammad Legenhausen, Juliane Hammer, Gregory Boyd and both editors of the book.
