God said to the Israelites, “I will take you as my own people, and I will be your God (Exod 6:7). Then God gave the Law which set apart Israel from the nations as God’s special people. Obedience to the Law was to be the distinguishing mark of the people of God and it was to be what sustained them in their relationship with God. However, this was a temporary covenant with a new covenant on the horizon which was prophesied by Jeremiah and Ezekiel. The new covenant to come was to be written on the heart and could be kept by those who walk in the power of the Spirit.
The Law pointed to the coming of Christ and with his coming, the Law is fulfilled. After Christ’s coming, the Law is no longer the distinguishing mark of the people of God. Rather, the people of God are distinguished by their faith in Jesus and by their participation in the Spirit within the new humanity where there is no distinguishing between Jew and Gentile. Thus, the specifics of the Law that separated Israel from the nations are no longer binding for the believer in Christ. There is a discontinuity of the Law, but there is continuity of the principles, values and morality that governed them. In this sense, the Law is “useful for teaching, rebuking, correcting and training in righteousness” (2 Tim 3:16). The NT believer is not obliged to carry out all the demands of the Law, but there are many lessons that can be drawn for Christian living from the Law.
