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. ~1 Peter 3:15-16
I've heard the first part of these verses many times, but usually not the second part (amazing how much insight you receive when you start diving into the verses around those you've heard all your Christian life!)
It says when you give your answer to do this with gentleness and respect. How many times when we are questioned regarding our faith do we get defensive or even arrogant? When asked about your faith do you remain gentle and respectful, even in the face of ridicule, mocking and even outright hatred?
