Our conscience is like a room which is subject to being kept clean or dirty. Just as the state of physical environment makes us breathe fresh air or otherwise so does a clear or seared conscience to our spiritual life. In looking through 1Peter 3: 15-16, we read: “But sanctify the Lord God in your hearts and always be ready to give a defense to everyone who asks for a reason for the hope that is in you, with meekness and fear, having a good conscience, that when they defame you as evildoers, those who revile your good conduct in Christ may be ashamed” NKJV MacArthur
We need to pattern our life according to the will of God learnt in the teachings of Jesus Christ. Christ summarized the Mosaic Ten Commandments into loving God and our neighbors. In other words, we are expected to do to others what we expect them to us. As it is, if it is the will of God for one to suffer for doing good, it is better than for doing evil” 1Peter 3:17 NKJV MacArthur. It is only by doing the will of God that one can have clear conscience before God and man. If one lies or commit any sin without anyone seeing or knowing; God is all eyes and sees all things done either in secret or under public glare. God had structured our conscience to commend or condemn us depending on what we do – good deed or otherwise.
As we continue to commit sinful acts, conscience gets seared and would no more be able to yield to the dictate for doing good deeds. 1Timothy 4: 1-2; “Now the spirit expressly says that in later times one will depart from faith, giving heed to deceiving spirits and doctrines of demons, speaking lies in hypocrisy, having their own conscience seared with hot iron”. Dirty or sacred conscience is a state of sinfulness or conscience cramped with lies, wickedness, drunkenness, contempt, adultery, fornication, covetousness and many more. Absalom’s was undoubtedly of this type of conscience.
Our conscience is the spirit of God in us. I believe, it represents the “still small voice” which many people often refuse to give due regard. In http://www.google.com it is described as “The nonphysical part of a person that is the seat of emotions and character, the soul.” Therefore, to be Christ-like, we need to seek harmony between body and spirit which must be kept clean and pure.
