In this blast from the past, J. Warner Wallace examines Biblical principles that can guide our response to heresy. What should we do when we encounter someone who holds a belief about God that is simply un-Biblical? Are we being divisive when we try to correct a fellow Christian? Shouldn't love and tolerance be our highest value and goal? Isn't it arrogant to think that we are right and others are wrong on matters related to faith? We'll answer these questions and address some listener email related to the Gospel of Mark and apparent Bible contradictions.
