Christianity is rational despite the fact that the mass majority of unbelievers consider it to be irrational. However, there are forms of Christianity whose proponents attempt to understand Man’s ability vs. his responsibility only via human reason. The correct way for Christians to view God, His ways, His Sovereignty, Man, Man’s depravity, and Man’s responsibility is to reason biblically. Here is an example. If our reason is exclusively extra-biblical then we say that Man’s ability and responsibility are coextensive. They must match up exactly. If not, then the supposition is irrational. This makes sense and is reasonable if our reasoning is extra-biblical, but is it right?
