God did rest on the 7th day. He gave that command to the children of Abraham. Those He lead out of Egypt.
That command was not mandated to the gentiles who also come to God through faith in Jesus.
In fact just the opposite was stated in regard to the sabbath by the one who didn't shrink back and gave the full counsel of God.
When you were dead in your sins and in the uncircumcision of your flesh, God made you d alive with Christ. He forgave us all our sins, 14having canceled the charge of our legal indebtedness, which stood against us and condemned us; he has taken it away, nailing it to the cross. 15And having disarmed the powers and authorities, he made a public spectacle of them, triumphing over them by the cross.
16Therefore do not let anyone judge you by what you eat or drink, or with regard to a religious festival, a New Moon celebration or a Sabbath day. 17These are a shadow of the things that were to come; the reality, however, is found in Christ
But as I see you post you follow your prophet Ellen White.
