Sonnet eh? Haven't read one by you. I have to say, structurally, I think you could do a lot more work towards making this as good a sonnet as possible. Remember the iambic pentameter is important, try not to abandon it so frequently or the flow could be harmed (and I believe that it was).
As for content, well, those 5 years are more than most people take to find God, so you should be proud of yourself for at least having an educated and tried faith, as opposed to a blind and unwavering one. As for me, Augustine couldn't restore my faith and Descartes is trying at the moment, so we'll see how that pans out.
Aside from the structural failings, nicely written, Frac. This deserves at least one reply.
"Faith" means the will to avoid knowing what is true.
