Covenant with God

Humans made a covenant with God two times, one time in Moses' times and the second one was made in Jesus's times. Humans have had no success in this world if they exchanged the contract with God.On the other hands, Faust made a contract with Mephistopheles in exchange for his soul, but he had regained his soul after his death even he succeeded in acquiring tens of interesting experiences in this world.You know Devil was one of archangels in heaven. He was a fallen angel. Devil symbolises the true figure of ambitious humans who succeeded in this world by opening a new frontier.Nothing happens if we kept on walking the path someone made.
