Just as Moses was the mediator of that covenant, and the laws that governed that covenant was called the law of Moses, so also Jesus is the Mediator of the New Covenant, and therefore it’s called the law of Christ.
But now He has obtained a more excellent ministry, inasmuch as He is also Mediator of a better covenant, which was established on better promises. Hebrews 8:6
But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, to an innumerable company of angels, to the general assembly and church of the firstborn who are registered in heaven, to God the Judge of all, to the spirits of just men made perfect, to Jesus the Mediator of the new covenant, and to the blood of sprinkling that speaks better things than that of Abel. Hebrews 12:22-24
For there is one God and one Mediator between God and men, the Man Christ Jesus.
1 Timothy 2:5
So it is no longer the law of Moses, who mediated that covenant, but Christ who is the Mediator of the new covenant administrates the law of Christ.
Bear one another’s burdens, and so fulfill the law of Christ.
Galatians 6:2
So when studying the New Testament precepts and principles we will come across phrases like, “His commandments“. His laws and commandments are about love; loving God and loving our neighbor.
For this is the love of God, that we keep His commandments. And His commandments are not burdensome. 1 John 5:3
If you love Me, keep My commandments. John 14:15
