Peter say, Sanctify the Lord God in your hearts: and be ready to give an answer to every man that asketh you a reason of the hope that is in you, with meekness and fear: Having a good conscience; that, whereas they speak evil of you, as of evildoers, they may be ashamed that falsely accuse your good lifestyle in Christ.
Your Conscience, that part of you that makes you aware of your actions as being morally right or morally wrong. There are four conditions of your conscience; Good:1Pet.3:16; Defiled:Titus 1:15; Seared: 1 Tim.4:2; or Poisoned: Heb.10:22
Conscience depends on knowledge, The truth of God’s Word. You are like a window that lets light in, but if the light is rejected the window becomes dirtier and dirtier to the point the light no longer penetrates the window. Which condition are you?
