New article: “How can I get a clear conscience?”
Conscience can be defined as “an inner feeling that acts as a guide to the rightness or wrongness of one’s behavior.” For those with a biblical worldview, the conscience is the part of the human soul that is most like God (Genesis 3:22). Those who disbelieve God have a difficult time explaining the existence of the human conscience. Evolution cannot account for this facet of the human spirit, which cannot be explained by a “survival of the fittest” mentality.
The conscience of man was awakened when Adam and Eve disobeyed God’s command and ate from the tree of the knowledge of good and evil (Genesis 3:6). Before that, they had known only good. The word knowing in Genesis 3:5 is the same word used elsewhere to describe sexual intimacy (Genesis 4:17; 1 Samuel 1:19). When we choose to “know” evil by intimate experience, our consciences are violated and emotional discomfort takes over. Whether we acknowledge God or not, we were created to have fellowship with our Creator. When we do wrong, we sense that we are at odds with our created purpose, and that feeling is deeply disturbing.
It was God whom Adam and Eve had offended; yet God Himself provided the solution to their violated consciences. He slaughtered an innocent animal to cover their nakedness (Genesis 3:21). This was a foreshadowing of God’s intended plan to cover the sin of all mankind.
