most of religious and church history has been largely preoccupied with religious ideas, about which you could be wrong or right. When faith is all about ideas, you do not have to be part of it; you just need to talk correctly about it. You never have to dive in and illustrate that spiritual proof is only in the pudding.
The spiritual question is this: Does one’s life give any evidence of an encounter with God? Does this encounter bring about in you any of the things that Paul describes as the “fruits” of the spirit: “love, joy, peace, patience, kindness, goodness, trustfulness, gentleness, and self-control” (Galatians 5:22)? Are you different from your surroundings, or do you reflect the predictable cultural values and biases of your group?
