Paul charges Timothy to remain faithful to the Scriptures he has known since childhood. His description of Scripture as God-breathed (theopneustos) provides the theological foundation for why the Bible is authoritative: it is not merely human reflection on God but God's own breath in written form.

From the writers we read together

John Lennox

Mathematician and Apologist, Oxford University

Lennox has spent decades arguing at the intersection of science and faith, and he consistently returns to the question of intelligibility: why is the universe ordered in a way that human minds can understand? His answer points to a rational God behind creation — and Scripture as the direct communication of that God to His image-bearers. Second Timothy 3:16 gives the mechanism: God breathed out words. What God breathed out at creation (the universe), He breathed out in history (the Scriptures).

The four purposes Paul names — teaching, reproof, correction, training in righteousness — form a complete curriculum for the spiritual life. Teaching gives truth; reproof shows where we have departed; correction re-sets the course; training in righteousness builds the muscle to walk it. The goal is not Bible knowledge for its own sake but completion: the man of God 'equipped for every good work.' Are you using Scripture for all four purposes, or only for the ones that feel comfortable?
