My daughter is a 21-Pilots fan. Proof: today she bought pre-sales tickets to their December show, where they will play music she hasn’t even heard yet because their album isn’t due out until next month. What if their new album is a terrible disappointment? She might have to sit through a whole concert of terrible music...
But her purchase is an act of faith. The good kind: reasonable, not blind. The kind that makes for good relationships. There's not an iron-clad guarantee but there are enough reasons to make it worthy of trust.
Her faith is based on good reasons: their prior performances, the music she has already heard, the interactions she has already enjoyed in the fandom, their demonstrated trustworthiness as people to date. So she has good reasons to trust that the boys will deliver a concert worth the price of entry. So she bought in.
My faith is based on good reasons: God’s prior performances (in demonstrably reliable histories, writings and prophecies), the ‘music’ I have heard already in this life (the good, true, beautiful, life-giving ways that really work), the interactions with God I have already enjoyed alone and together with other believers, the demonstrated trustworthiness and wisdom of God’s character. I have plenty of good reasons to trust that God will deliver a Life worth whatever price he asks of me. So I bought in.
Some disparage “faith” per se as if it is blind, based on nothing. Some people seem to blindly believe cliches and assumptions, but these days I’d say that's far more likely among the agnostics of main-stream culture than among the Christians who go against the flow. Most Christians I know have had to challenge the mainstream cliches and assumptions, and have come to my daughter’s kind of faith, a reasonable and well-founded relationship.
When people actually examine the reasons for this kind of faith, they often become ready to buy in.
The Limits of Proof
The Phenomenal and the Noumenal - Noumenal realities are important and life-directing. Yet the more noumenal a reality is, the greater the need for good and sufficient reasons. Good reasons are there. Go get 'em.
