The Bible is God’s “owner’s manual” for living. Therefore, He would not have given us something beyond our ability to reason. Admonitions such as “husbands, love your wives,” and “do not get drunk,” are pretty straightforward. How many ways can such things be understood?
For this commandment that I command you today is not too hard for you, neither is it far off. It is not in heaven, that you should say, “Who will ascend to heaven for us and bring it to us, that we may hear it and do it?” Neither is it beyond the sea, that you should say, “Who will go over the sea for us and bring it to us, that we may hear it and do it?” But the word is very near you. It is in your mouth and in your heart, so that you can do it. (Deuteronomy 30:11-14)
God Himself says that His word is not that tough to figure out. So it’s not that the Bible is hard to understand; it’s that we make our own conscience as the moral standard and the Bible’s simplicity interferes with our desire to do something different.
All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work. (2 Tim 3:16, 17)
Those who reject the Bible say something like, “No one really knows what it means. A thousand people can come up with a thousand different conclusions. Who knows which one is right? I’m not gonna listen to any of it. I’ll let God sort it out in the end.”
These folks prefer the Bible to remain closed, not because they want to be bothered with racking their brain trying to sort out the truth, but because they don't want to face their guilt and therefore be exposed by the Word. (John 3:19, 20) They want to do what they please and not be subject to a moral code. Liberals and so-called “free thinkers” hate the Good Book because it generally condemns whatever they’re trying to promote.
