How do we know the importance of scripture for believers?

The importance of scripture for believers is articulated in 2 Timothy 3:16-17, which states that all scripture is God-breathed and profitable for doctrine, reproof, correction, and instruction in righteousness. This passage reveals that scripture serves as the foundation for a believer's growth in understanding God's nature, their own sinfulness, and the righteousness found in Christ. For believers, engaging with scripture leads to wisdom unto salvation and spiritual maturity, as they are equipped to live out their faith in a manner that pleases God.
