This summary of the regulations of the law shows that they all had one thing in common: they were carnal ordinances; they did not in themselves touch the soul. A person could go through all these rituals and their heart could be completely unaffected.
There are those religions today still which perform many outward washings and rituals cleaning ceremonies, which teach their people to distinguish between food they may eat and foods they may not eat, as if the kingdom of God consisted in eating and drinking (Romans 14:17). Islam has gone back to the Old Testament restrictions of the law without understanding that these things can make no real difference to the soul. Water removes dirt from the body, but it cannot wash sins from the soul and the conscience. The eating or not eating certain foods makes no difference when it comes to holiness before God. Righteousness is about motive and goal and adherence to God’s standards, not about what food enters the stomach. Christ released his disciples from all such powerless regulations when he said, ‘That whatsoever thing from without entereth into the man, it cannot defile him; Because it entereth not into his heart, but into the belly, and goeth out into the draught, purging all meats? And he said, That which cometh out of the man, that defileth the man. For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders, Thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness: All these evil things come from within, and defile the man ((Mark 7:18-23).
Why does the Scripture teach that these regulations were to be followed by Israel for ever (Exodus 12:14; 27:21; etc.)? These passages speak of the regulations of the law being imposed on the generations of Israel without end. How then could they cease with the coming of Christ? What ceased was only the outward observance of these regulations. Their real significance lay in the spiritual lesson which they were designed to teach. Every one of these ordinances had a spiritual lesson behind it, and this lesson will indeed never cease; it continues to be observed and practiced by the church today which is the true Israel of God.
