The New Testament is based on the New Covenant God revealed in Jeremiah 31:31-34, and Ezekiel 36:27. This was repeated by Paul in Hebrews 8:10-13. The SDA's try to cling to the Old Covenant, which Paul says is old, growing decrepit and near to disappearing. It came alongside the promised blessing given to Abraham, but has the status of a slave bringing forth children of the flesh and of slavery, not like the free wife who brings forth children of Promise, children of the Spirit (Galatians 4:21+). They miss the Spirit which God promised to put into us in Ezek. 36:27, and which began to be fulfilled in John 20:22. This is the Spirit, which was promised to write God's laws on our heart and inscribe them on our minds in the New Covenant. This is the Spirit that frees us from the law of sin and death as Paul describes in Romans 8:2. A day as a day of Sabbath rest is the shadow, which is cast by Christ as the real Sabbath rest. "Come unto Me...I will give you rest."
