2Tim 3:17 NLT
God uses it to prepare and equip his people to do every good work.
God wants to use you in his redemption story of the world. His word points to the change he wants to do in your heart so that you can be used in his redemptive plan.
God wrote you an amazing true story through history and 1 bible in 66 books to point to Christ.
He wants to change your heart to reconcile you to God and allow you to be a part of the story of how he redeems the world.
