What does the Bible say about the importance of doctrine?

Scripture places significant importance on sound doctrine, which serves as a foundation for the church and believers’ faith. In 2 Timothy 4:2-4, Paul exhorts Timothy to preach the word, to be prepared in season and out, correcting, rebuking, and encouraging with patience and careful instruction. This is crucial because people will increasingly turn away from sound teaching and seek what aligns with their desires, leading to confusion and error. Without a clear standard of doctrine, believers risk drifting away from the truth of the gospel, which may ultimately lead them to eternal destruction.
