In our study of revelation (God’s revealing Himself and His will to us), we are making the point that some of that communication is to all people at all times. This is called “natural revelation,” meaning that God speaks through creation, human nature, and human history.
Someone has said, “Pity the poor atheist who, upon seeing a glorious sunset, has no one to thank!” Nature and its beauties is one venue of God’s communicating information about Himself and His characteristics to all people everywhere.
Another avenue through which God speaks to everyone is man’s conscience. After speaking about the witness of creation in Romans 1, Paul touches on man’s conscience in Romans 2 where he writes: “They show that the work of the law is written on their hearts, while their conscience also bears witness, and their conflicting thoughts accuse or even excuse them.” (v. 15).
We often know what is right and wrong based on that inner voice God implanted within us. James 4:17 says, “So whoever knows the right thing to do and fails to do it, for him it is sin.” We can choose to ignore our conscience.
I’ve also noticed in my life that my conscience has also been tainted by sin. Sometimes I’m extremely sensitive to things that don’t matter — and insensitive to things that do. For that reason, I tell other Christians, “Don’t swallow the dictum ‘Let your conscience be your guide.’ Our consciences are also fallen. Rather follow this truth: ‘Let your conscience, shaped by the Word of God, be your guide!’”
God speaks to man through his conscience. C.S. Lewis’ masterful work Mere Christianity gets to the heart of this issue when he writes about right and wrong. He writes, “Human beings, all over the earth, have this curious idea that they ought to behave in a certain way, and can not really get rid of it.” (Mere Christianity, Book 1, Chapter 1, paragraph 11). Lewis later writes, “It seems, then, we are forced to believe in a real Right and Wrong. People may be sometimes mistaken about them, just as people sometimes get their sums wrong; but they are not a matter of mere taste and opinion any more than the multiplication table. Now if we are agreed about that, I go on to my next point, which is this. None of us are really keeping the Law of Nature. If there are any exceptions among you, I apologise to them. They had much better read some other work, for nothing I am going to say concerns them. And now, turning to the ordinary human beings who are left . . .”
What is your conscience telling you to do or not do today? Then, if it is consistent with the Word of God, obey it!
