In Leviticus 18 the people being treated now as a holy people, everything that was contrary to the order of God in nature is here strictly and solemnly prohibited. It is important to hold the same principle always. God does not absolve from that which offends His natural order.
Grace may bring us into a higher place, where we do not use our liberty as to nature; but God habitually maintains His own order there; and so should we. Grace, I repeat, may withdraw one from the operation of it because of a higher call, as for instance in the service of God. We see this in the case of Paul himself; nevertheless was there any one who more firmly and distinctly held fast the wisdom, the propriety, the holiness of God’s order in nature, than that man who through grace had been lifted above it? Hence we have simply the prohibition of what was contrary to God’s will here below. Neither Egypt nor Canaan must regulate the practice of Israel: He who spoke to them was Jehovah their God, who, as He laid down the broadest principles, knew how to descend into the smallest details which concerned His people.
“Leviticus” is not given by divine inspiration: it is merely a name taken from the Greek version; in short it is a human name. I do not hesitate therefore to make the remark. The Hebrew mode of reference to these books was the mere citation of the first word in each book. In the book of Numbers then, where we have the walk on earth set forth, service finds its capital seat. In the book which develops access to God priesthood is as prominent as here Leviteship. A remark applies as to priesthood exactly similar to what we found true of Leviteship; namely, that the Christian, who in one point of view is of Israel and in another a Levite, is no less a priest. Only priesthood sets forth the drawing near to God Himself in the heavenly sanctuary – no longer the figure, but the true – the antitype; whereas Levitical service has to do with the service of the sanctuary whilst the people of God are passing through the earth.
It is clear from this that the priestly functions of the believer have a very much higher character than his Levitical service, if we would express ourselves in the language of types. In the one case we have to do with God Himself; we draw near in the sense of what Christ is to Him as well as to us. In the other we have that which is a holy duty; nevertheless it is a duty which has to do with man and the earth in our passage through this world. It is of this latter that we are about to hear more particulars. In the flesh, and accordingly the various requirements of God were suitable to their place. Our condition is altogether different. We “are not in the flesh but in the Spirit, if so be that the Spirit of God dwell in us.” Christ has Himself brought us into a heavenly position. This is the meaning of what He says in John 17: “For their sakes I sanctify myself.” Not as if there ever was or could be the smallest thought of evil in Christ’s nature, or in any of His ways, I need nor say; nor as if He were here thinking of the mighty work of redemption by which He has set us apart to God. This is not its meaning; but the place that He has taken according to the dignity of His person and the results of His work for us – His place in heaven, that He might be there as man in that new scene – not only lifted up from the earth, but in the glory of God above, and consequently stamping a heavenly character upon us who know Him there. It is well to make this remark, because Christian holiness is bound up with the place where we know Christ now, when we come to look at it in its full character according to God’s mind.
