The Bible never tells us to take a blind leap of faith into the darkness and hope that there's somebody out there. The Bible calls us to jump out of the darkness and into the light. That is not a blind leap. The faith that the New Testament calls us to is a faith rooted and grounded in something that God makes clear is the truth.
R. C. SproulThe more faithful preachers are to the Word of God in their preaching, the more liable they are to the charge of hypocrisy. Why? Because the more faithful people are to the Word of God the higher the message is that they will preach. The higher the message, the further they will be from obeying themselves.
R. C. SproulThe Word of God can be in the mind without being in the heart; but it cannot be in the heart without first being in the mind.
