This is one of the best Islam-Christianity short talks we have ever heard, in which two different concepts of God are compared and contrasted.
Dr. William Lane Craig clearly shows how the God of Islam is morally deficient, while by contrast the God of the Bible is morally perfect. This perfection is brought into focus in particular within the trinity.
This last point about the trinity is especially interesting because Muslims are often quick to attack the trinity, while Christians are often reluctant to defend the trinity before Muslims. Dr. Craig shows that, in fact, the trinity is a great asset to Christianity as a cohesive and coherent set of beliefs.
