What does the Bible say about holding onto faithful doctrine?

In Titus 1:9, Paul instructs leaders to hold firmly to the trustworthy message as it has been taught, indicating that sound doctrine is crucial for the health of the church. This instruction not only applies to elders but to all believers, as the message of Christ is the foundation of faith. Holding onto this faithful doctrine allows leaders to encourage others with sound teaching and to refute those who contradict the truth. It underscores the belief that the power of the church lies not in human wisdom but in the authority of God’s Word.
