He is a Jew, which is one inwardly, and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God (Romans 2:29).
God’s law is His word, it’s His written instructions for believers to adhere too. Many think because of grace, we’re no longer under the law. Through Jesus, grace was given so that we would not receive what we deserve when we sin. In order to express His nature (holiness, truth and justice), God must punish sin. Since sin personally offends God, no one should be surprised that sin makes God angry. To deny His anger is to reject the necessity of Christ’s reconciling work on the cross.
The New Testament is not contradictory to the Old Testament Law; rather it is the ultimate fulfillment of the spiritual intention of the law. Where the law degenerated into legalism among the Pharisees, Jesus takes the law beyond mere outward observance to the inner spiritual intention of God. Prior to the Hebrews deliverance from Egypt, the Hebrews entered into a covenant with Yahweh through Moses. So that His people might fulfill their covenant obligations. Yahweh gave them the Ten Commandments. The first four commandments concern the relationship between God and His people; the remainder deal with human relationships.
Moses was God’s instrument in giving His law to Israel. It was not really “the Law of Moses, but the law of God. The law was meant to protect Jews from pagan corruptions. God has not annihilated the law, He has removed it from the life of the believer because it can neither save nor sanctify. The unsaved man, however, still lies under its convicting and condemning work (But we know that the law is good, if a man use it lawfully. Knowing this, that the law is not made for a righteous man, but for the lawless and disobedient, for the ungodly and for sinners, for unholy and profane, for murderers of fathers and murderers of mothers, for manslayers. For whoremongers, for them that defile themselves with mankind, for menstealers, for liars, for perjured persons, and if there be any other things that is contrary to sound doctrine – 1st Timothy 1:8-11). The first three pairs of violations recall the first four commands which address a person’s relationship with God. The proper function of the law is to make sinners aware of their sinfulness.
If the law refers to the Law of Moses, the Pentateuch, then the passage is referring to the way Jesus completely fulfilled the requirements of the law. If law is the the entire Old Testament, then the gospel fulfills the promises of the coming of Jesus Christ, and the forgiveness of sin. If law is the moral law, then the gospel fulfills it because it is through Jesus that people are empowered by the Holy Spirit to live in a way that pleases God. Jesus didn’t come to destroy the law, but to fulfill the law (Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfill – Matthew 5:17). The law is to show us our transgression against God and His word, Apostle Paul explained how the law showed him his sins (For I was alive without the law once: but when the commandment came, sin revived, and I died. And the commandment, which was ordained to life, I found to be death. For sin, taking occasion by the commandment, deceived me, and by it slew me. Wherefore the law is holy, and the commandment holy, and just and good – Romans 7:9-12). The word of God is His law, and He expects us as believers, who has been circumcised in our hearts to submit ourselves to His instructions. We’re the spiritual Jews when we have been born of His Spirit, and we must adhere to His written word. Take the time and read His instructions, you will find life for His word is life and they are spiritual.
