Rightly dividing God’s word begins with seeing and honoring the contrast God makes between the two great covenants of the Bible.
The first or Old Testament was fulfilled when Jesus met the requirement of it, by paying the price for sin with His own blood. (Co.2:14; Mt.5:17-19; Ro.6:23; He.2:9,10)
The New Testament is now in force instead of the Old (He.10:5-9). Thus we keep the commandments of the New Will and Testament of Christ. (He.9:14-18)
Men living today are not to be judged by the Old Law given to Israel. (Co.2:14-23). We will be judged concerning faithfulness to the New Testament or words of Christ. The Gospel is the Law for all men of every nation. (Mt.28:18-20; Mk.16:15,16). Jesus said, He that rejecteth me, and receiveth not my words, hath one that judgeth him: the word that I have spoken, the same shall judge him in the last day (Jn.12:48).
While the Old Law was indeed God’s, it was given for old Israel to follow until Christ would come (Ga.3:16,19,22-29; He.10:1-10). We are blessed to live under the New Testament. HJS
