What does the Bible say about listening to sound doctrine?

The Apostle Paul emphasizes the importance of sound doctrine in 1 Timothy 1:3-4, where he instructs Timothy to charge others to teach no other doctrine. This highlights the necessity for believers to focus on the true message of salvation through Christ alone. Preaching any doctrine that strays from this truth is deemed a fable, as such teachings can lead to spiritual damage and distractions from God's word. In 2 Timothy 4:2, Paul further commands preachers to focus on sound doctrine, as it is through this that God saves His people.
