30:15-20 What could be said more moving, and more likely to make deep and lasting impressions? Every man wishes to obtain life and good, and to escape death and evil; he desires happiness, and dreads misery. So great is the compassion of the Lord, that he has favoured men, by his word, with such a knowledge of good and evil as will make them for ever happy, if it be not their own fault. Let us hear the sum of the whole matter. If they and theirs would love God, and serve him, they should live and be happy. If they or theirs should turn from God, desert his service, and worship other gods, that would certainly be their ruin. There never was, since the fall of man, more than one way to heaven; which is marked out in both Testaments, though not with equal clearness. Moses meant that same way of acceptance, which Paul more plainly described; and Paul's words mean the same obedience, on which Moses more fully treated. In both Testaments the good and right way is brought near, and plainly revealed to us.I call heaven and earth to record this day against you,.... Either, literally understood, the heavens above him, and the earth on which he stood, those inanimate bodies, which are frequently called upon as witnesses to matters of moment and importance; see Deuteronomy 4:26; or figuratively, the inhabitants of both, angels and men:

that I have set before you life and death, blessing and cursing; had plainly told them in express words what would be the consequence of obedience and disobedience to the law of God; long life, and the blessings of it in the land of Canaan, to those that obey it; death, by various means, and dreadful curses, to those that disobey it; of which see at large Deuteronomy 28:16,

therefore choose life, that thou and thy seed may live; that is, prefer obedience to the law, and choose to perform that, the consequence of which is life; that they and their posterity might live comfortably and happily, quietly and safely, and constantly, even to the latest ages, in the land of Canaan.
