Faith is a natural power. Strong faith develops as a positive feedback between employing that faith and benefit in daily life.
When we are certain what we need to do to advance we just do it. We don’t often stop to admire the great faith we just used in that endeavor.
When we face roadblocks and uncertainty, sages offer their advice. Ultimately we try out their advice because we had some faith they might be right. If we win, we call this substituting faith for wisdom. If we lose, we try out best to gather some learning from the debris. If we lose and cause others to suffer as well, we re-define the sage as an evil manipulator (think Hitler or Jim Jones).
Faith itself is nothing special. The correctness or incorrectness of your object of faith is what ultimately matters.
A correct object of faith will provide happiness for yourself and others AND through positive feedback in a natural gradual progression strengthen your power of faith and make your life force more dynamic and your ability to weather hardship more resilient.
This emphasis on benefit in daily life as opposed to some fanatical adherence to dogma is what attracted me to Buddhism. I have an aversion to “spiritual” mumbo jumbo so I also must perceive rational philosophical underpinnings AND a concrete basic practice I can embrace directly without intermediaries.
I found all this with the Nichiren Buddhism practiced by the SGI organization.
