At my core, I am a very indecisive person and unless I spend time praying and studying, my faith sometimes falters.
I do empathize with what Singer47 says. Our faith is an element of our temperament and character which connects it to our tendencies to become depressed. I respect the points of view of people whether they are faithful, agnostic, atheist, etc but I do like what Dalai Lama said, "Our prime purpose in life is to help others. And if you can't help them, at least don't hurt them." I have known atheists/agnostics who live as morally as those of us who seek direction from God. When we do foolish things, the results are less than desirable. Faith can help you make better choices and find more peace in your heart and that helps me when I am depressed.
