According to scripture, we are not under the law (Romans 6:14) are dead to the law (Romans 7:4, Galatians 2:19) and have been delivered from the law (Romans 7:6) as concerning condemnation.
True enough.
But there has been a lot of misunderstanding by Christians who have not clearly understood what Paul was saying when he said that "we are not under the Law" (by implication the Law of Moses). All of the above is true, yet we need to have a very clear understanding of what it means to be under the Law of Christ (also called "the Law of Faith", "the Royal Law", "the Law of Love", and "the Law of Liberty").
Many have mistakenly assumed that the Law of Moses was "bad". And that is simply not the case. When speaking about the entire Law of Moses, the Holy Spirit says through Paul that the Law is (1) holy, (2) just, (3), good, and (4) spiritual. Yet many Christians have missed all this.
Since the Law of Moses includes the Ten Commandments, all of this would be applicable to them, as well as to the many moral and civil laws given to Israel. All the commandments pertaining to the tabernacle (and temple), the Levitical priesthood, the sacrifices and offerings, the feasts, festivals, and holy days, the ceremonial observances, etc. were
all good in their place and for as long as the Law was in effect (until the day Christ died).
In the meantime, the scribes, Pharisees, doctors, and lawyers had made the Law burdensome, and also misrepresented it to suit their own carnal ideas. Furthermore they had started teaching that a sinner could be justified by the works or deeds of the Law. All of this had to be addressed in the Gospel.
Furthermore, Christ came to "fulfil the Law". But the term "the law" has several applications, and all of those were included in this matter. Not only is
the Law of Moses called the Law, but the entire
Torah (five books) is called the Law, and in many places the entire
Tanakh (24 books corresponding to out 39 books of the OT) is also called the Law. Christ fulfilled the Law by (1) being perfectly obedient to it, (2) fulfilling all the types and shadows of Himself, (3) fulfilling five of the feasts of Israel, (4) fulfilling all the animal sacrifices as the Lamb of God, and (5) fulfilling the perfect work of atonement which could not be fulfilled otherwise, so that there is no more sacrifice for sins.
In view of this, God made the Law of Moses (the Old Covenant) obsolete, and established the Law of Christ (under the New Covenant). Which means that Ten Commandments are as applicable to Christians as they are to the whole world. The difference is that God has given the believer the gift of the Holy Spirit, and it is by the power of the Spirit that the children of God can fulfil the Law (through agape love). Christ summed up the entire Law of Moses in the two greatest commandments, then distilled those two commandments into His one great commandment -- the commandment to love God and to love others as Christ loves them.
This Law is even more demanding than the Law of Moses, since it requires self-sacrifice and total surrender to God and Christ.
