God gave a law to Moses and the children of Israel at Mount Sinai. The law essentially began with the Ten Commandments and went on with detailed instructions (Ex. 20; Lev.). The law given at Sinai governed Israel for centuries to come. For instance, God told Israel not to intermarry with pagans, lest they turn Israel’s heart away from God (Ex. 34:16). When Solomon was on the throne four hundred years later, this was still God’s law (1 Kgs. 11:1-4). Five centuries after Solomon, during the time of Nehemiah, God still required the Jews to remain separate from the idolatrous people around them (Neh. 13:23-27).
Further, God prohibited men from touching the ark. He gave this law at Sinai and it still stood in the time of David—as Uzzah found out (Num. 4:15; 2 Sam. 6:6, 7). God commanded the Israelites to observe the Sabbath (Ex. 20:8-11). He expected this to be honored as long as the Law of Moses stood (Neh. 13:15-22). When God gave the Law, no man could ignore or alter it in any way. What was true when it was given was true 100, 200, or 1,000 years later.
While man could not alter or do away with the Law, God could—and did—because He is the Law-Giver. He removed the Law of Moses to bring in the Law of Christ (Col. 2:14, 15; Eph. 2:14, 15; Heb. 7:12-14; 2 Cor. 3:3-13). God gave a new law, the New Testament, through Jesus Christ (Matt. 26:26-28; Heb. 8:10-12). It was given in the first century A.D. Though it was given long ago, it still stands and will until the end of time.
What God said about belief still stands. We must believe in God and His Son Jesus Christ (Heb. 11:6; Jn. 8:24). We will be held accountable to this truth even though we may ignore it—even though it is 19 centuries later.
What God said about baptism still stands. He said we must believe and be baptized to be saved (Mk. 16:16). Through Peter He said we must repent and be baptized to have our sins remitted (Acts 2:38). Again, He said through Peter that baptism saves us (1 Pet. 3:21). No man or group of men can alter or ignore this truth without coming under the wrath of God.
What God said about the church still stands. He said the church is the body and there is only one body (Eph. 1:22, 23; 2:16; 4:4). He said there is peace in this one body (Col. 3:15). There is no peace with God outside of that one body. There is no other body in which to find fellowship with God. No denomination or religious organization other than the church of the New Testament is acceptable to God—regardless of what men say. In other words, not all churches are right—only one, the church of Christ (Matt. 16:18; Rom. 16:16).
What God said at Sinai was true 1,000 years later and had to be observed by Israel. What God said in the first century is still true today and must be honored by all men. The Law of God stands!
