WHY do we have the Bible?
For everything that was written in the past was written to teach us, so that through endurance and the encouragement of the Scriptures we might have hope
2 Timothy 3:15-18
15 and how from infancy you have known the holy Scriptures, which are able to make you wise for salvation through faith in Christ Jesus. 16 All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, 17 so that the man of God may be thoroughly equipped for every good work.
We have the Bible to give us hope, to make us wise for salvation through faith in Christ Jesus, to teach us in righteousness, so that we may be people of God and equipped to do good work.
