“What if I have doubts about my faith? What should I do?”
I’m going to try to answer this in a very general way, since
you don’t specify any particular issue that is troubling you.
I like to think of faith as that not-quite-quantifiable thing
that bridges the gap between the evidence I already have in front of me and
my will to act on that evidence. That’s not a theological definition, but it
works for me. Properly understood, the biblical definition,
“the assurance of things hoped for, the conviction of things not seen,” seems to me to amount to much the same thing.
