I am in a state of, "I don't know if I believe in God".
Do you feel it, so you believe? Do you have rational reasons for believing? Do you believe in all the stories in your books, if you have them, and why?
Do you ever doubt that God may exist? How often do you think about God?
Faith is deciding to trust in hope, and to live accordingly.
Faith in God is not about being convinced of anything. It's about identifying the concept of God that you would hope to be true, and then deciding to trust in that hope with your thoughts, words, and actions. If doing so makes you a better person, and your life experience a better experience, then stick with it. If not, change the ideal you're hoping for and try again.
I don't know if God exists, or what God's nature might be if God exists. But I have determined for myself that love, forgiveness, kindness and generosity are "divine traits" within my experience of existence. So I choose to believe that these traits are reflections of a divine realm, or of a "divine being" if there is such a thing. And that's all I need. I can place my trust in those traits and try to live my life as an expression of them. And in doing so, I find that I am a better person, and that my life is significantly improved, for me and for everyone around me.
Faith isn't about pretending to have all the answers. It's about trusting in what we would hope to be the truth even though we don't know that it is. And then seeing if trusting in that hope works for us.
