Adam Clarke Bible Commentary
Leviticus 18:30
Verse 30. Shall ye keep mine ordinance] The only way to be preserved from all false worship is seriously to consider and devoutly to observe the ordinances of the true religion. He who in the things of God goes no farther than he can say, Thus it is written, and thus it behoves me to do, is never likely to receive a false creed, nor perform a superstitious act of worship.
1. How true is that word, The law of the Lord is PERFECT! In a small compass, and in a most minute detail, it comprises every thing that is calculated to instruct, direct, convince, correct, and fortify the mind of man. Whatever has a tendency to corrupt or injure man, that it forbids; whatever is calculated to comfort him, promote and secure his best interests, that it commands. It takes him in all possible states, views him in all connections, and provides for his present and eternal happiness.
2. As the human soul is polluted and tends to pollution, the great doctrine of the law is holiness to the Lord: this it keeps invariably in view in all its commands, precepts, ordinances, rites, and ceremonies. And how forcibly in all these does it say, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength; and thy neighbour as thyself! This is the prominent doctrine of the preceding chapter; and this shall be fulfilled in all them who believe, for Christ is the end of the law for righteousness to them that believe.
Reader, magnify God for his law, for by it is the knowledge of sin; and magnify him for his Gospel, for by this is the cure of sin. Let the law be thy schoolmaster to bring thee to Christ, that thou mayest be justified by faith; and that the righteousness of the law may be fulfilled in thee, and that thou mayest walk, not after the flesh, but after the Spirit.
