I suppose it makes me feel as if maybe the whole thing is actually a sham and there's no more to it than a handy club that we all belong to.
Ok I get this. But what is the club for?
I worry that I live a private holiness and am not active in trying to bring about God's kingdom on earth. I pray. I try and connect with something beyond myself, i try and figure out Jesus.
I do now have faith because for so long I didn't and the change has been quite mind blowing.
I think faith is for different things depending on your circumstances. For some people its all about mission, for some its support, for some its community, some want to live in hope, some think about life after death, some try and be better people, some want to change the world, some people just want to praise God. Most of us get a few of these things. Theres more no doubt that I haven't listed.
I also like what father mike Schmitz says about losing faith. He says we dont lose faith, we choose not to use it, or we give our attention to other things than God.
It seems to me God must be fairly central to your life if you are searching like this. Essentially you are being called and you are trying to answer and make sense of it all.
So keep going.
Another way to think about it is that the way you feel now is the holy spirit moving in you. You might not be shaking in the aisles but you are being drawn to live your life... better? You can see what you dont want (praising God but not living the teachings of Jesus). This gets you closer to what you do want. And hopefully closer to God.
Sorry for long rambling post.
