You might want to reread that. Nowhere does it state that we keep the Sabbath to be saved.
HERE....
However because we are saved we Worship GOD and not idols. We do not take the LORD'S name in vain. We keep Sabbath. We do not kill or bear false witness. We honor our fathers and our mothers. We do not steal, covet or commit adultery.
GOD is Love. Love fulfills the Law and as HE is so are we in this world. Because It is HE that works in us both to will and do HIS good pleasure. Christ in us the hope of Glory.
And you still haven't addressed the facts related in the post.
um, a blind person can see in the above that you attached Sabbath keeping for salvation.
