Why is God's Word important for understanding doctrine?

The significance of Scripture in doctrine cannot be overstated; as 2 Timothy 3:16 states, 'All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness.' This highlights that the doctrines of Christianity are derived not from human wisdom or tradition, but from divine revelation. The Bible serves as the ultimate authority on matters of faith and practice. It is through the study of God's Word that believers can discern truth, develop sound doctrine, and be assured of their beliefs in an ever-changing cultural landscape.
