2 Peter 1: 19-21
The Bible is God's Word, the cornerstone of all that a Christian believes. If we fail to build our faith on the Bible, or let other ideas creep into our foundation, our whole life will crumble. We must know about the Bible before we can discuss with non-believers why it is our cornerstone.
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.
