Buy the Truth and Sell It Not
One of the most important attitudes one can have in striving to go to heaven is that of intense zeal for the truth of God. Too often, people settle on something far less than the truth. Remember, a counterfeit, though it may look relatively genuine, is nevertheless worthless. Likewise, we cannot enjoy the benefits of truth just by getting pretty close. We must take our position firmly and foursquare on the truth. "Ye shall know the truth and the truth shall make you free" (John 8:32).
There are many among us who, like Pilate, would ask, "What is truth?" (John 18:38). Many do not believe in absolute truth. The Bible, however, is absolute, unchanging truth. "Forever, O Lord, thy word is settled in heaven" (Psalms 119:89). The belief that there is absolute truth is fundamental to one who desires to "buy the truth and sell it not" (Proverbs 23:23).
One Can Be Wrong
It is a fact that anyone can mistakenly be wrong. Paul, when speaking of his past manner of life, before his conversion, said, "I have lived before God in all good conscience until this day" (Acts 23:1). Yet he was before a "persecutor, and a blasphemer, and injurious" (1 Timothy 1:13). How could he have lived in all good conscience when he had been so wrong? The answer is simple. He thought he was right. "There is a way which seemeth right unto a man, but the end thereof are the ways of death" (Proverbs 16:25). The fact that we can be wrong means that it does not behoove us to close our minds to further investigation. Jeremiah said, "Stand ye in the ways, and see, and ask for the old paths, where is the good way, and walk therein, and ye shall find rest unto your souls" (Jeremiah 6:16).
Faith vs. Opinion
Naturally, study brings us to certain conclusions. All of us live by certain principles. But upon what do our conclusions rest? All too often they rest upon mere opinion. Realize that if something is a matter of faith, then God must have said something about it. We cannot know the words of eternal life by opinions. One man's opinion is just as good as another man's; but no man's opinion is worthy to be compared to God's.
You would not want to risk crossing the ice over a river merely because somebody thinks you can. Neither should we risk trying to go to heaven by the opinions of men. The difference between an opinion and conviction is that an opinion is usually a spur-of-the-moment conclusion someone comes up with based upon skimpy premises, if any. A conviction is a conclusion based upon evidence which has been thoroughly studied and meditated upon. God has given us a wonderful book. It furnishes man with doctrine, reproof, correction, instruction in righteousness, that he may be complete, furnished completely unto every good work (2 Timothy 3:16-17).
The Bible is our evidence. It is the truth. When believed, it becomes subjective faith. The Bible did not come from men, so there need be no question about its reliability. It was given unto men though, and designed so they could understand it when they read it (Ephesians 3:3-5). This is not to say that all the Bible is simple to understand. There are difficult portions of it that demand much study. The matters of conversion to God and everyday living are simple and easy to understand. What many find difficult about such matters is the application of that which may be so simple to understand.
Feelings — A Poor Standard
Do not base your conviction upon some peculiar feeling you might have. Feelings are a poor standard of truth. We have already mentioned Paul. We might mention Jacob also who believed with all his heart that his son Joseph was dead, but that did not make it true. Remember, God has given us revelation, facts. Our convictions must rest upon these facts or else we will find ourselves upon shifting sand.
Conscience — Not a Reliable Guide
Neither is conscience a reliable guide in determining whether your convictions are sound or not. The conscience is very pliable to begin with. Our conscience is usually formed at a tender age. At that time it may be trained to approve good or evil. When we reach maturity our conscience alters and becomes almost unchangeable. From then on it tells us only whether we have done as we learned to do or not.
Changing the conscience then is a slow, difficult project. If your conscience were trained correctly, well and good. If it were trained incorrectly, then it will approve even when you do things that are really wrong, because it was taught that which was wrong. "Let your conscience be your guide" is therefore poor advice.
This brings us back again to the fact that we must ultimately make our stand upon the word of God. Everything is to be judged by it.
