Romans 2:14-16, Power of the Human Conscience
It is interesting, Apostle Paul observed, God made man with a conscience that is able to judge his own actions by the law which God placed in his heart. He knows good from evil, right from wrong, having a moral conscience within him. If he does wrong, his conscience gives him no peace. And if he is right, he knows there is no rebuke against him. It is a faculty of self-reflection and self-judgement that God places in man that enables him to evaluate himself honestly.
How is that possible? Because God made man in His very image – Genesis 1:26 And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.
Before I became a Christian, I found myself lacking, deficient, but could not tell what was lacking! Observe how the Apostle Paul is preparing to present the gospel to the unsaved by revealing what God has marvellously done to create man with a God-given conscience. He presents to us the intimate and endearing place we have in the sight of our Creator God.
