If we say we believe the Bible because “it is a reliable collection of historical documents written by eye-witnesses to supernatural events that took place in accordance with specific prophecies demonstrating that the Bible is divine in origin, oh, and it works,” we have given the other solid, objective reasons to trust the Bible supplemented by our subjective experience that it works.

If Christianity were founded on a collection of personal experiences (sensing/experiencing God) then it would be pretty weak/vague much like new-age mysticism, or belief in some cosmic force (cue Imperial March). I would likely disbelieve many of the specific claims made about who God is and so forth.

Fortunately it isn’t founded on personal experiences alone, although personal experience does play a role in that we can know “it works”. 1 Peter 3:15-16
