Seek-
I had religion and spirituality confused (and still do at times) for a long time.
As strange as it sounds 12 step work has really helped me with the Higher Power concept in a way that nothing else has.
It also got me over the hump of fear of religious implications to try meditation which has been very good to me. I see prayer as me talking to a higher power, and meditation as a way to be open to listening for what I might get back....
Finally for me it got easier when I made it simple. I love a very flawed being. If as a human I can love this flawed being so much I can extrapolate out that there is probably something bigger than me that can love me even with all my flaws. That is very comforting to me, and I have only discovered it in the last year or so.
Finally I don't know if this is Higher Power stuff or not, but I will say that when I look as my life (especially the hard part) as lessons that help my growth I seem to keep it in balance a little better.
