There are lots of threads floating around the forums these days arguing for and against God's existence.
God has not made her presence known to me in my life. I see no reason to need to believe in her in order to be happy, to reason, to behave ethically, or to understand how things work.
Perhaps God judges our fate in the afterlife? If there is some life beyond death in which she will judge me, I have no control over my fate, as I don't even know what the nature of such an afterlife would be, or by what criteria I'll be judged. Humans offer lots of opinions on that subject, but none has presented a convincing argument that demonstrates they are any more in the know on the subject than I am. So I have no reason to live my life any differently based on what may or may not happen beyond death.
In short, even if God does exist...does it matter?
I think that's a really great question.
I began wide ranging explorations of the great thinkers/teachers/traditions/ways to live to find possible insights ways to live a full and wonderful life. Here and now.
To really live, instead of only half way.
So I read very widely, such as Lao Tzu, Emerson, and many others, and tried many ways people have developed to be more fully alive, from meditation to dance to sweat lodges to yoga to Hindu chanting, and on and on.
Of course, that included in time the words of the very famous teacher Jesus (as in the gospels accounts of his sayings).
Maybe there are 3 really compelling reasons some might want to find out whether God exists.
(And actually an way to find God has been given and makes total sense too:
Jeremiah 29:13 You will seek Me and find Me when you search for Me with all your heart.
-- a kind of all-in with the heart and soul, a total...act of trust, which is 'faith'.
Now to search I'd start by listening to someone that knows of God better than others, so that would be Jesus, right off the bat, as you notice when you begin to read what He said, that he's the kind of person that would know.)
