Why is sound doctrine significant for churches today?

Sound doctrine is significant for contemporary churches because it serves as the foundation for teaching that aligns with God's Word. In 2 Timothy 4:3, Paul warns that there will be a time when people will no longer endure sound doctrine, preferring teachings that align with their desires. This highlights the need for churches to commit to sound doctrine to avoid falling into error and deception. By holding fast to sound teaching, churches can nurture a community of believers who are rooted in truth, fostering growth in faith and unity in the body of Christ. It encourages healthy spiritual development and equips the church to fulfill its mission.
