No arguments really, my faith is personal to me, and based on personal experience. Put simply, a loving god was there for me when I needed Him most, and has been there ever since.
I was brought up a Catholic. No brainwashing or coercion, religion in my family was something you wore like a loose fitting garment. I turned my back on all that when I was 14 though, because religious observance didn't really fit with my teenage aspirations; I was too busy trying to be Jack Kerouac, and Jack was too cool for school, or church.
I was never an atheist, for the idea of a godless universe always seemed intuitively absurd; but my thinking for a long time was that if there was a god, all that had nothing to do with me. I was quite contemptuous of religious folk (that's the ego for you), but I never completely turned my back on the possibility of the miraculous or the divine.
A few decades on and, thanks to alcoholism and some spectacularly bad decision making engendered thereby, I found myself needing a miracle. When I was finally desperate enough, and my pride was humbled enough, to beg God for help and completely abandon myself to Him (or Her), not on my terms but on God's, the miracle happened. And I've been witnessing miracles of healing, in my life and in others', ever since. But then, since I have been trying on a daily basis to develop and to rely upon the God consciousness that I believe is within us all, I have come to view all of life as a kaleidoscope of miracle and wonder. And this has been true even in the most difficult circumstances.
