At every level of the physical and spiritual, we must approach based on faith! This means as you keep the sabbath holy, you are engaging in the act of faith at the very highest level, because the Creator is also the Savior. So, we have a double mystery, creation, and salvation housed in the very same person – Jesus Christ. We must come to him by faith. Sabbath-keeping is an expression of faith at the highest level,–faith in conversion, which is spiritual creation, and faith in the physical creation which is how the Creator made the heaven and the earth.
