Having a good conscience; that, whereas they speak evil of you, as of evildoers, they may be ashamed that falsely accuse your good conversation in Christ.
Having a good conscience - the spring of readiness to give account of our hope. Hope and flood conscience go together, Acts 24:15-16. Profession without practice has no weight. But those who have a food conscience can afford to give an account of their hope 'with meekness.'
Whereas - (1 Peter 2:12.)
Falsely accuse, х epeereazontes (G1908)] - malice shown in deeds as well as words; "despitefully use," Matthew 5:44; Luke 6:28,
Conversation - conduct.
In Christ - the element of your life as Christians: it defines 'good.' It is your good walk as Christians, not as citizens, that calls forth malice (1 Peter 4:4-5; 1 Peter 4:14).
