Most Christians believe God is in control, but they are unsure of how to reconcile that control with their struggles with sin, with the command to evangelize, and with the immense suffering in the world and their own lives.

Laing offers an introduction to the doctrine of providence based on the theory of middle knowledge, first articulated in the sixteenth century. This view describes how creatures have true free will and God has perfect knowledge of what each creature could and would do in any circumstance. Middle knowledge helps answer the most perplexing theological questions: predestination and salvation, the existence of evil, divine and human authorship of Scripture, and science and the Christian faith. Laing provides extensive biblical support as well as practical applications for this theology.
