The apostle Paul tells Timothy something amazing about the bible in Second Timothy 3:16-17, he tells him:
“All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness; so that the man of God may be adequate, equipped for every good work.”
Paul is saying here that the whole bible is God-breathed! You can trust God to tell you the truth and let Jesus show you the way.
