1 Peter 3:15-16

15 but sanctify 1Christ as Lord in your hearts, always being ready 2to make a defense to everyone who asks you to give an account for the 3hope that is in you, yet 4with gentleness and 5reverence;
16 and keep a 6good conscience so that in the thing in which 7you are slandered, those who revile your good behavior in Christ will be put to shame.
