If a god exists who cares about you trust that that being will give you the faith you need. As a non god you arent expected to spontaneously generate faith . Get on with living and if a caring god takes an interest in you then your question will be answered. Dont sweat faith.
This has been my philosophy since leaving. I got to the point where I stopped looking for evidence to support my faith, and left it up to him/her. If God wants my faith, he/she need only to reveal themselves. I'm not wasting another minute of my life searching.
