This paragraph closes the legislation of this book, the succeeding chapters being in the nature of an epilogue or appendix. It sums up the whole law, makes plain its inmost essence and its tremendous alternatives. As in the closing strains of some great symphony, the themes which have run through the preceding movements are woven together in the final burst of music. Let us try to discover the component threads of the web.
The first point to note is the lofty conception of the true essence of the whole law, which is enshrined here. 'This commandment which I command thee this day' is twice defined in the section (vs.16, 20), and in both instances 'to love Jehovah thy God' is presented as the all-important precept. Love is recognised as the great commandment. Leviticus may deal with minute regulations for worship, but these are subordinate, and the sovereign commandment is love. Nor is the motive which should sway to love omitted; for what a tender drawing by the memories of what He had done for Israel is put forth in the name of 'Jehovah, thy God!' The Old Testament system is a spiritual system, and it too places the very heart of religion in love to God, drawn out by the contemplation of his self-revelation in his loving dealings with us. We have here clearly recognised that the obedience which pleases God is obedience born of love, and that the love which really sets towards God will, like a powerful stream, turn all the wheels of life in conformity to His will. When Paul proclaimed that 'love is the fulfilling of the law,' he was only repeating the teaching of this passage, when it puts 'to walk in His ways,' or 'to obey His voice,' after 'to love Jehovah thy God.' Obedience is the result and test of love; love is the only parent of real obedience.
The second point strongly insisted on here is the blessedness of possessing such a knowledge as the law gives. Verses 11-14 present that thought in three ways. The revelation is not that of duties far beyond our capacity: 'It is not too hard for thee.' No doubt, complete conformity with it is beyond our powers, and entire, whole-hearted, and whole-souled love of God is not attained even by those who love Him most. Paul's position that the law gives the knowledge of sin, just because it presents an impossible elevation in its ideal, is not opposed to the point of view of this context; for he is thinking of complete conformity as impossible, while it is thinking of real, though imperfect, obedience as within the reach of all men. No man can love as he ought; every man can love. It is blessed to have our obligations all gathered into such a commandment.
Again, the possession of the law is a blessing, because its authoritative voice ends the weary quest after some reliable guide to conduct, and we need neither try to climb to heaven, nor to traverse the wide world and cross the ocean, to find certitude and enlightenment enough for our need. They err who think of God's commandments as grievous burdens; they are merciful guide-posts. They do not so much lay weights on our backs as give light to our eyes.
Still further, the law has its echo 'in thy heart.' It is 'graven on the fleshly tables of the heart,' and we all respond to it when it gathers up all duty into 'Thou shalt love the Lord thy God,' and our consciences say to it, 'Thou speakest well.' The worst man knows it better than the best man keeps it. Blurred and illegible often, like the half-defaced inscriptions disinterred from the rubbish mounds that once were Nineveh or Babylon, that law remains written on the hearts of all men.
A further point to be well laid to heart is the merciful plainness and emphasis with which the issues that are suspended on obedience or disobedience are declared. The solemn alternatives are before every man that hears. Life or death, blessing or cursing, are held out to him, and it is for him to elect which shall be realised in his case. Of course, it may be said that the words 'life' and 'death' are here used in their merely physical sense, and that the context shows (vs.17, 18) that life here means only 'length of days, that thou mayest dwell in the land.' No doubt that is so, though we can scarcely refuse to see some glimmer of a deeper conception gleaming through the words, 'He is thy life,' though it is but a glimmer. We have no space here to enter upon the question of how far it is now true that obedience brings material blessings. It was true for Israel, as many a sad experience that it was a bitter as well as an evil thing to forsake Jehovah was to show in the future. But though the connection between well-doing and material gain is not so clear now, it is by no means abrogated, either for nations or for individuals. Moral and religious law has social and economic consequences, and though the perplexed distribution of earthly good and ill often bewilders faith and emboldens scepticism, there still is visible in human affairs a drift towards recompensing in the world the righteous and the wicked.
But to us, with our Christian consciousness, 'life' means more than living, and 'He is our life' in a deeper and more blessed sense than that our physical existence is sustained by His continual energy. The love of God and consequent union with Him give us the only true life. Jesus is 'our life,' and He enters the spirit which opens to Him by faith, and communicates to it a spark of His own immortal life. He that is joined to Jesus lives; he that is separated from Him 'is dead while he liveth.'
The last point here is the solemn responsibility for choosing one's part, which the revelation of the law brings with it. 'I have set before thee life and death, the blessing and the curse, therefore choose life.' We each determine for ourselves whether the knowledge of what we ought to be will lead to life or to death, and by choosing obedience we choose life. Every ray of light from God is capable of producing a double effect. It either gladdens or pains, it either gives vision or blindness. The gospel, which is the perfect revelation of God in Christ, brings every one of us face to face with the great alternative, and urgently demands from each his personal act of choice whether he will accept it or neglect or reject it. Not to choose to accept is to choose to reject. To do nothing is to choose death. The knowledge of the law was not enough, and neither is an intellectual reception of the gospel. The one bred Pharisees, who were 'whited sepulchres'; the other breeds orthodox professors, who have 'a name to live and are dead.' The clearer our light, the heavier our responsibility. If we are to live, we have to 'choose life'; and if we do not, by the vigorous exercise of our will, turn away from earth and self, and take Jesus for our Saviour and Lord, loving and obeying whom we love and obey God, we have effectually chosen a worse death than that of the body, and flung away a better life than that of earth.
