Question: "Why is sound doctrine so important?"
Answer: Paul charges Titus, “You must teach what is in accord with sound doctrine” (Titus 2:1). Such a mandate makes it obvious that sound doctrine is important. But why is it important? Does it really make a difference what we believe?
Sound doctrine is important because our faith is based on a specific message. The overall teaching of the church contains many elements, but the primary message is explicitly defined: “Christ died for our sins according to the Scriptures [and] . . . he was raised on the third day according to the Scriptures” (1 Corinthians 15:3-4). This is the unambiguous good news, and it is “of first importance.” Change that message, and the basis of faith shifts from Christ to something else. Our eternal destiny depends upon hearing “the word of truth, the gospel of your salvation” (Ephesians 1:13; see also 2 Thessalonians 2:13-14).
Sound doctrine is important because the gospel is a sacred trust, and we dare not tamper with God’s communication to the world. Our duty is to deliver the message, not to change it. Jude conveys an urgency in guarding the trust: “I felt I had to write and urge you to contend for the faith that was once for all entrusted to the saints” (Jude 1:3; see also Philippians 1:27). To “contend” carries the idea of strenuously fighting for something, to give it everything you’ve got. The Bible includes a warning neither to add to nor subtract from God’s Word (Revelation 22:18-19). Rather than alter the apostles’ doctrine, we receive what has been passed down to us and keep it “as the pattern of sound teaching, with faith and love in Christ Jesus” (2 Timothy 1:13).
Sound doctrine is important because what we believe affects what we do. Behavior is an extension of theology, and there is a direct correlation between what we think and how we act. For example, two people stand on top of a bridge; one believes he can fly, and the other believes he cannot fly. Their next actions will be quite dissimilar. In the same way, a man who believes that there is no such thing as right and wrong will naturally behave differently from a man who believes in well-defined moral standards. In one of the Bible’s lists of sins, things like rebellion, murder, lying, and slave trading are mentioned. The list concludes with “whatever else is contrary to the sound doctrine” (1 Timothy 1:9-10). In other words, true teaching promotes righteousness; sin flourishes where “the sound doctrine” is opposed.
Sound doctrine is important because we must ascertain truth in a world of falsehood. “Many false prophets have gone out into the world” (1 John 4:1). There are tares among the wheat and wolves among the flock (Matthew 13:25; Acts 20:29). The best way to distinguish truth from falsehood is to know what the truth is.
Comment: In these last days, many have rejected sound bible doctrine and their itching ears have gone after error and false teaching. It is so bad that many actually get angry as they reject sound doctrine and sound teaching. They start screaming "judgmental" and "pharisee" when they hear truth. Sadly, there are few saved in these last days and the false tares are getting very easy to spot.
