If you’re searching for that perfect line of logic capable of subduing any objection, you’re wasting your time. There is no magic, no silver bullet, no clever turn of thought or phrase that’s guaranteed to compel belief…We have very limited control over how other people respond to us.That’s largely in God’s hands. We can remove some of the negatives or dispel some of the fog—and we ought to try to do both. But at the end of the day, a person’s deep-seated rebellion against God is a problem only a supernatural solution can fix. —Greg Koukl  (from: When Your Argument Lacks Impact)
