1 Peter 3: 15-16
Peter famously failed to defend his faith three times in one night. From that point on, he encouraged his fellow Christians to be equipped to do so, not for themselves, but for the difference it can make in the lives of those that question or challenge us.
Where it was once easy to claim our Christian faith without resistance, today's world will challenge our beliefs and call our faith into question. This is why we must be able to defend our faith and beliefs by knowing why we take a stand there.
