1 Peter 3:15-16 But in your hearts revere 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. 

Do I always have the reason for my hope prepared at a moment’s notice? Lord, when this happens, enable me to be prepared and to be respectful, gentle, and kind.
