14 But even if you should suffer for the sake of righteousness, you are blessed. And do not fear their intimidation, and do not be in dread,
15 but sanctify Christ as Lord in your hearts, always being ready to make a defense to everyone who asks you to give an account for the hope that is in you, but with gentleness and respect;
16 and keep a good conscience so that in the thing in which you are slandered, those who disparage your good behavior in Christ will be put to shame.
1 Peter 3:14-16
What is conscience? God has put within each one of us something that cries aloud against us, whenever we do that which we know to be wrong. Conscience is the detective that watches the direction of our steps and decries every conscious transgression. Conscience is a vigilant eye before which each imagination, thought, and act, is held up for either censure or approval.
I believe there is no greater argument for the existence of God in the world today than conscience. There is no greater proof of the existence of a moral law and Lawgiver in the universe than this little light of the soul. It is God’s voice to the inner man. Conscience is our wisest counselor and teacher, our most faithful and most patient friend.
