Part of the debate over God's existence centers on questions about the possibility and "provability" of miracles. Collins begins by presenting and contrasting the options within traditional Christian theism. Collins then explores the biblical passages that support a classically theistic foundation and relates these results to the corresponding philosophical, theological, scientific, and apologetic questions that it raises.

By bringing together what the Bible teaches about miracles; "nature," "cause," and special divine action, Collins effectively takes on the God-of-the-gaps position and answers with a persuasive "yes" the crucial question of whether it is intellectually responsible to embrace the biblical view of God's action in the world.
