I feel the presence of God in every tree, in every sunset, in every new snow, full moon, everytime I celebrate Winter Solstice, Easter in a Unitarian Universalist tradition, and when I feel overwhelming love and good among human kind.
I was agnostic until I had a friend with whom I discussed everything from chemistry, evolution, quantum physics to the Bible and my beliefs as a UU. One day I just let go of my doubt and went, doi! God is everywhere and has created such an incredible Universe for us. And it all clicked for me!
During meditation, I feel God always.
