Hello Philanty,
Once you're open to the possibilities then spirit/intuition will lead you to the path that's best for you. The decision (free will) to go down a specific path IS having faith in the path you took. If you chose to go down the path of Reiki then you're saying that you have faith in that Reiki will help those in need. Hopefully this clears the muddy waters a bit ;)
Amen to you,
Archangel
