You say you want to have faith in God or some sort of gods. It seems like you haven't had spiritual experiences. Either you're begging for something you don't have, or you want an explanation for something you already believe in. Why do you believe there is a god or gods?
God has watched everything. He is watching us right now. However, he has ALREADY watched us. The future is God's past. While we are all situated in a simulation of a free state, or an existence with free nature, or as my religion calls it, "free agency," yes, although this freedom exists, God has ALREADY watched the outcome of this freedom experiment we're playing and he ALREADY has an opinion of us. God knew in the beginning that some people would believe in him and some wouldn't. Those who more bravely believed in God in the preexistence gained momentum that plays out in our present lives. If you feel you lack faith, perhaps you weren't as brave in the preexistence.
But you want faith. And that counts for something. Perhaps you did something in the preexistence such as that you had to be tested in this life to do God's will not having a sure knowledge.
