In Exodus 33:13, Moses wanted God to be gracious to him by teaching him to walk in His way that he and Israel might know Him, in 1 Kings 2:1-3, God taught how to walk in His way through the Law o fMoses, and in Matthew 7:23, Jesus said that he would tell those who are workers of lawlessness to depart from him because he never knew them, so the goal of the Law of Moses is to graciously teach us how to know God and Jesus by walking in His way, which is the narrow way to eternal life (John 17:3).@Soyeong. I think you're reading Romans 10 differently than Paul intended.
Paul's argument isn't that Christians are required to keep the Law of Moses. He has just stated that "Christ is the end (goal or fulfillment) of the law for righteousness to everyone who believes" (Romans 10:4). When he quotes Deuteronomy 30, he immediately identifies it as "the word of faith which we preach" (Romans 10:8), applying Moses' words to the gospel rather than returning believers to the Mosaic Covenant.
in Romans 9:30-10:4, the Israelites had a zeal for God, but it was not based on knowing Him, so they failed to attain righteousness because they misunderstood the goal of the Law of Moses by pursuing it as though righteousness were earned as the result of their works in order to establish their own instead of pursuing the Law of Moses as through righteousness were by faith in Christ, for knowing Christ is the goal of the Law of Moses for righteousness for everyone who has faith. In Romans 10:5-16, Paul referred to Deuteronomy 30 as the word of faith that we proclaim in regard to proclaiming that the Law of Moses is not too difficult for us to obey, in regard to proclaiming that obedience to it brings life and a blessing, in regard to what we are committing to obey by confessing that Jesus is Lord, in regard to the way to believe that God raised him from the dead for salvation, and in regard to the way to obey the Gospel.
Again, the Gospel that Jesus taught in Matthew 4:15-23 called for our obedience to the Law of Moses. in Titus 2:14, Jesus gave himself to redeem us from all lawlessness and to purity for himself a people of his own possession who are zealous for doing good works, so the way to believe in the Gospel that Jesus spent his ministry teaching and in what he accomplished through the cross by God raising him from the dead is by repenting and becoming zealous for doing good works in obedience to the Law of Moses (Acts 21:20).
@Jack claimed that nobody obeys the Law of Moses and the point of citing Joshua and Luke was to show that there are examples in the Bible of people who did obey it. Jesus spent his ministry teaching his followers to obey the Law of Moses by word and by example and the reason why he established the New Covenant was not in order to nullify anything that he spent his ministry teaching, in order to nullify what he accomplished through the cross, or in order to free us to continue to have the same lawlessness that caused the New Covenant to be needed in the first place, but rather the New Covenant still involves following the Law of Moses (Jeremiah 31:33, Ezekiel 36:26-27).The examples from Joshua and Luke describe people living under the Old Covenant before Christ's work on the cross. They don't establish that New Covenant believers remain under the Law of Moses.
It is contradictory to think that our righteousness comes through faith in God's Word made flesh and not through following his example of embodying God's Word. God has not commanded anything that is not in accordance with walking in the Spirit, but rather God's character traits are the fruits of the Spirit and the Law of Moses is God's instructions for how to know Him through embodying His character traits, which is why the Spirit has the role of leading us to obey it (Ezekiel 36:26-27). Likewise, in Romans 8:2-7, Paul contrasted the Law of the Spirit with the law of sin and death and contrasted those who walk in the Spirit with those who have minds set on the flesh who are enemies of God who refuse to submit to the Law of God. The Son is the radiance of God's glory and the exact likeness of His character (Hebrews 1:3), which he embodied through his works by setting a sinless example for us to follow of how to walk in obedience to the Law of Moses/how to walk in the Spirit.The New Testament consistently teaches that while the Law is holy and reveals God's character, our righteousness comes through faith in Christ, and believers are led by the Spirit rather than being under the Mosaic Law (Romans 6:14; Galatians 5:18; Romans 7:6).
In Romans 5-8, Paul described the Law of God as being something that is the good that he wanted to do in contrast with describing the law of sin as being something that was causing him not to do the good that he wanted to do. In Romans 6:14, Paul described the law that we are not under as being a law where sin had dominion over us, which is clearly not describing something that is the good that Paul wanted to do, but rather that is the role of the law of sin. In Romans 6:15, being under grace does not mean that we are permitted to sin, and in Romans 7:7, the law of sin is not sinful [unlike the law of sin, which is sinful], but how we know what sin is, so we we are still under the Law of God, but are not under the law of sin.
In Romans 7:22-23, Paul said that he delighted in obeying the Law of God in contrast the the law of sin, which was waging war against the law of his mind and held him captive. So it would be absurd to interpret Romans 7:5 as referring to the Law of God as if Paul delighted in stirring up sinful passions in order to bear fruit unto death, but rather that is the role of the law of sin. Likewise, it would be absurd to interpret Romans 7:6 as if Paul delighted in being held captive to sin, but rather it is the law of sin that he described as holding him captive.
In Galatians 5:16-23, Paul contrasted the desires of the flesh with the desires of the Spirit and everything that he listed as works of the flesh that are against the Spirit are also against the Law of Moses while all of fruits of the Spirit are aspects of God's character traits that the Law of Moses was given in order to teach us how to embody. Moreover, the desires of the flesh causing us not to do the good that we want to do is how Paul described his struggle with the law of sin in Romans 5-8. In Romans 8:2-7, the law that we are not under when we are led by the Spirit is the law of sin and death, not the Law of God. The Law Moses was given by God and the Spirit is God, so it would be contradictory to interpret Galatians 5:18 as referring to the Law of Moses as if we are not led by God when we are led by God.
It is contradictory to point to God's Word made flesh instead of pointing to his example of embodying God's Word.So I don't agree that Romans 10 is calling Christians back under the Law of Moses but pointing them to Christ, in whom the Law finds its fulfillment.
