How do we know that adhering to sound doctrine is important?

The Apostle Paul warns of the dangers posed by false teachers in Philippians 3 and throughout his epistles. He underscores the necessity of holding fast to the same doctrine passed down through the ages, as it is a measure of spiritual safety. Sound doctrine comes from Scripture and is essential for discernment amidst the conflicting teachings of the world. By remaining faithful to the historic truths of Christianity, believers are safeguarded against misleading innovations that compromise the essence of the gospel and lead them away from Christ. Thus, it is crucial for churches to maintain fidelity to Scripture and embrace the doctrines that define the true faith.
