1st Peter 3:15, 16 says, "But in your hearts set apart Christ as Lord. Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect, keeping a clear conscience, so that those who speak maliciously against your good behavior in Christ may be ashamed of their slander. Tell why you believe that there is a God and why you believe in Christ. On what do you base your faith?
