God’s plan and purpose relevant to the Torah, the Sabbath, in the New Covenant,
Nothing about the Law or ordinances or dietary mandates or days or festivals wins favor or righteousness with God the Father…these were a shadow of the Messiah that was to come (Colossians 2:16). When Jesus entered Time, His primary goal was to destroy the works of the Devil (1 John 3:8b) and provide victory over sin, death, Hell, the grave, through grace and faith for those who believe in Him as Messiah. Also, Jesus came to free mankind from an arduous and condemnative Law that defined culpability void atonement (Romans 3:20; Galatians 3:10).
The Law of the Covenant, the Torah, was a sign-post indicating mankind’s inability to please a Holy and Righteous God through works and self-righteousness as this was first demonstrated in Genesis 3:21 via the fig leaves used in an futile attempt to mask sin. In the New Covenant, the primary focus is upon “relationship”…not Law or days or ordinances or diet…but love and intimacy with God the Father by grace through faith in Jesus as Lord and receiving the indwelling Holy Spirit as the SEAL and Guarantor of that relationship, forever.
The New Covenant is about a Sabbath fulfilled in Jesus as our REST and our PEACE through the Spirit. The Law in the New Covenant is for the defiled and defines their culpability before God while God’s desire for His children in the New Covenant is intimacy/relationship with Him through sanctification via the Holy Spirit given to all who believe in Jesus as Messiah > the One who suffered and died to pay our sin-debt – a debt we could not pay ourselves.
