You appear to have a very personal relationship with God. Would you please remove these from me, show me unequivocally that you are here, and you are Love. So I don't know if you ever stop having some form of doubt. It's the nature of the mind to do that. But I think we can make some pretty good inroads into establishing a foundation of faith from which we live, rather than a foundation of fear.
Faith is like a muscle.
You practice and it gets stronger. Here's my chance to practice faith. You use your faith muscle, and it works. So the next time something comes up, it's a little easier to practice faith. Then sooner or later you find yourself having faith in situations that years ago would have knocked you off your rocker.
