The Relevance of the Sinai Commandments for the Christian,
The Sinai Commandments, nine of ten, excluding the 4th – a ceremonial law, are based on the moral law of conscience (Romans 2:14-15) extant from the creation of the angels forward as an arbiter of free will. The laws at Sinai were given the Hebrew Tribes as they were inundated with a pagan people serving pagan gods and affiliation with same had the potential to deter Elohim’s eschatological plans concerning His Messiah through Judah and the “Great Commission” via the Gospel used as a battle strategy “to destroy the works of the devil” (1 John 3:8b).
The Commandments were never given to the Gentile Nations but they do exist as an example of Elohim’s holiness and His righteousness and they are to be used as a tutor, as a teacher, as an instrument of guidance to lead one to faith in Jesus and HIS righteousness, a righteousness earned for us by Jesus as He, alone, kept the Commandments in mandated perfection (James 2:10; Galatians 3:10).
It is by faith, trust in Jesus as our Lord, not through law-keeping, that we can receive the righteousness of Jesus imputed into our life by covenant promise (2 Corinthians 5:21; John 3; Hebrews 8:12); subsequent establishing covenant relationship with the Father by faith, the indwelling Holy Spirit begins a work of sanctification, a setting apart of the redeemed (Ephesians 1:13-14) concerning obedience via the human conscience, not codified law but the Spirit’s anointing empowering the faithful through the conscience to please the Father through love and honor and dignity in accordance with His will (Galatians 5:16).
This “new creation” concerning mankind and obedience (2 Corinthians 5:17) is NOT possible through vain attempts to keep the Commandments (Romans 3:20) but a right standing, covenant relationship, with the Father is only possible by receiving Messiah’s righteousness imputed, gifted, over one’s life by trusting-believing in Messiah Jesus as Lord; that is, believing that Jesus died to pay your sin-debt owed the Father (John 3)…a sin-debt mankind could never pay in the flesh through works of attempted obedience to the Sinai Commandments (Ephesians 2:8-9; Galatians 2:16; Romans 8:1-2; James 2:10; Galatians 3:10).
