Verse 16.— Having a good conscience. By doing what a good conscience approves, we have a good conscience. This good conscience God approves. To keep or hold fast such a conscience is accomplished by never denying the faith and by being always careful to do what God requires at our hands. While in this condition we possess a tower of strength when assailed by persecution.Accuse your good conversation in Christ. When your. Christian course and conduct are falsely called evil, the purity of your life, the strict conformity thereof to the Christ model is an all-sufficient answer, and fully enough to shame all your accusers.
