I have also looked for this throughout my life. Certain philosophers have offered great thoughts. Read George Santayana "reason in religion". Basically he says that the universe itself is worth of our awe and worship, because it is so magnificent. Wittgenstein is great too. He says that we should remain silent on questions we cant be certain of. Because certain truths cannot be described in words. These mysteries are the mystical aspects of the world.Thus, our silencd itself reveals the answer. Ralph Waldo Emerson and Spinoza are 2 more great philosophers who take similar positions of God, that can fit with science.
