I wish I had a nickel for every time I have heard someone relate all the ways that the O.T. ordinances contributed to the Israelites’ health. It is true that they did this—there is even a book about it called, None of These Diseases. But, the fact is that they never knew about the health aspects of the rules about latrines, no pork and other dietary regulations, quarantines, etc. For them, these were rules that had no value other than God said so, and to them the purpose was to draw a line that determined whether one would go his own way or God’s way.
Certainly, God knew the health purposes but that was not his purpose either. When I pointed that out in a Bible class, the teacher was shocked. I responded that since God lifted the dietary and other restrictions and did not bind them on the church, did that mean he cared more for the health of the apostate Jews than he did for that of obedient Christians? In effect, by allowing the church to ignore these regulations, he denied them all the health benefits of the O.T. ordinances. Did he love the church less than the Jews in that for more than a millennium and a half until medical discoveries by men, his people died from their failure to follow those ordinances? History reveals that neither the Jews nor others discovered the relationship of these rules to health until the advent of modern medicine.
God’s true purpose was to distinguish between the holy and the common, to firmly establish that such a distinction exists and to teach men to value the holy. Further, these requirements define “Holy” as whatever God says it is. Men may never understand why. So, when we come to the N.T. ordinances [literal meaning, “requirements”] how do you react? Do you decide such things are not really significant—as long as one follows the main issues regarding the deity of Jesus and grace and faith, then such things as instrumental music, use of the church’s money, method of baptism, church organization, etc. really do not matter? Or, is your attitude expressed by the phrase, “I will be holy because God is holy?”
Since we are to be a spiritual people with new hearts (Ezek 36:26; Gal 4:6) our diet consists of the things we read, watch, hear, etc. From the Movies and TV shows, I have heard discussed after church, had our people lived under the Law of Moses, they would have been eating a little pork now and then because it is not really like worshipping a different God or coveting. From the dress of both men and women, we who are priests would have ignored the restrictions placed on the High Priest's clothing as "not in style" and having nothing to do with true worship.
God looked on their hearts just as he did on David's, "You shall love the LORD your God with all your heart and with all your soul and with all your might. And these words that I command you today shall be on your heart" (Deut 6:5-6).
God looks on our hearts too, "Finally, brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things. " (Phil 4:8). God commands mind-control to maintain holiness of heart.
"but as he who called you is holy, you also be holy in all your conduct, since it is written, “You shall be holy, for I am holy.” And if you call on him as Father who judges impartially according to each one's deeds, conduct yourselves with fear throughout the time of your exile, " (1Pet 1:15-17).
