2 Timothy 3:16,17; Hebrews 4:12; 2 Peter 1:19-21 - The Bible is our authority, period! Not because it's well written (though it is). Not because it's the most reliable "holy book" ever written (though it is). Not because its instructions have been proven to be life's best decisions (though they are). Rather, it's because of where (or who) it came from. If we start with that, it makes more sense, it calms our fears, it saves our lives.
