Seventh-day Sabbath Left in No Uncertainty—We have the positive word of God in regard to the Sabbath [Exodus 31:12-18quoted]. (3SM 318.1) MC VC

Is it possible that so much importance can be clustered about those who observe the Sabbath, and yet no one can tell when the Sabbath comes?

The fallacy of the day line is a trap of Satan to discourage. I know what I am speaking about. Have faith in God. Shine where you are, as a living stone in God’s building. (3SM 318.5) MC VC
