Don’t know about the proof but it all seems to makes sense.
The Tables of Stone and their Message from God.
As we have seen, this discovery proves that Jesus confirmed the New Covenant with His own blood and water, in the same way as Moses confirmed the Old Covenant with the blood and water of animals. But what does it mean, that the covenant was confirmed? Millions of Christians today are taught that the law was done away with at the cross, but this discovery is scientific and physical evidence that the law was in fact confirmed a the cross as a part of the covenant. We saw in Chapter 4 how Christ confirmed that the disciples were a part of the covenant. How the sacrifice was a part of the New Covenant, and how the blood was a part of the New Covenant, and now we see how the law was also confirmed as a part of the New Covenant. When Moses sprinkled the blood and water above the law, he was signifying that the law now had to be kept, and was a part of the Old Covenant. Thus, when Christ sprinkled His blood and water above the law, He too was signifying that the law now had to be kept, and is a part of the New Covenant. There is a law that the Bible says was done away with at the cross, but what some Christians do not realise is that the Bible speaks of at least two different laws. One is the law of the Ten Commandments, and the other is the sacrificial, ceremonial laws. It is only the sacrificial, ceremonial laws that were done away with at the cross. We do not need to conduct sacrificial ceremonies anymore, as they symbolised Christ, and He has already been sacrificed, “Having abolished in his flesh the enmity, even the law of commandments contained in ordinances” Ephesians 2:15. But the law of the Ten Commandments were confirmed by the blood and water of Christ, and Galatians 3:17 says that once a law is confirmed, it cannot be changed and it cannot be done away with, “Though it be but a man's covenant, yet if it be confirmed, no man disannulleth, or addeth thereto.” Furthermore, Galatians 3:15 says that it was indeed the law that was confirmed as a part of the New Covenant, and this law cannot be done away with, “And this I say, that the covenant, that was confirmed before of God in Christ, the law… cannot disannul, that it should make the promise of none effect.” Every word that was confirmed by the blood and water of Christ, was written on two tables of stone by the finger of God. And every word of that law was recorded in Exodus 20. So every word of Exodus 20 cannot be changed and cannot be done away with. Millions of Christians are taught that the second commandment has been done away with. The second commandment says, “Thou shalt not make unto thee any graven image… Thou shalt not bow down thyself to them, nor serve them…” and this commandment cannot be changed or done away with. It doesn’t matter if it is a statue or icon or picture of Buddha, Krishna, or even Mary or Jesus. We must not make them and we must not bow down to them, or pray to them. Millions more Christians are taught that the fourth commandment has been changed. The fourth commandment says, “Remember the Sabbath day to keep it holy, six days shalt thou labour and do all thy work, but the seventh day is the Sabbath to the LORD thy God, in it thou shalt not do any work…” and that commandment cannot be changed and cannot be done away with. The seventh day is Friday evening to Saturday evening, but millions of Christians are falsely taught that it has been changed to Sunday.
