11 Surely, this commandment that I am commanding you today is not too hard for you, nor is it too far away. 12 It is not in heaven, that you should say, "Who will go up to heaven for us, and get it for us so that we may hear it and observe it?" 13 Neither is it beyond the sea, that you should say, "Who will cross to the other side of the sea for us, and get it for us so that we may hear it and observe it?" 14 No, the word is very near to you; it is in your mouth and in your heart for you to observe.

15 See, I have set before you today life and prosperity, death and adversity. 16 If you obey the commandments of the Lord your God that I am commanding you today, by loving the Lord your God, walking in his ways, and observing his commandments, decrees, and ordinances, then you shall live and become numerous, and the Lord your God will bless you in the land that you are entering to possess. 17 But if your heart turns away and you do not hear, but are led astray to bow down to other gods and serve them, 18 I declare to you today that you shall perish; you shall not live long in the land that you are crossing the Jordan to enter and possess. 19 I call heaven and earth to witness against you today that I have set before you life and death, blessings and curses. Choose life so that you and your descendants may live, 20 loving the Lord your God, obeying him, and holding fast to him; for that means life to you and length of days, so that you may live in the land that the Lord swore to give to your ancestors, to Abraham, to Isaac, and to Jacob.

Matthew Henry's Commentary on Deuteronomy 30:11-20

Commentary on Deuteronomy 30:11-14

(Read Deuteronomy 30:11-14)

The law is not too high for thee. It is not only known afar off; it is not confined to men of learning. It is written in thy books, made plain, so that he who runs may read it. It is in thy mouth, in the tongue commonly used by thee, in which thou mayest hear it read, and talk of it among thy children. It is delivered so that it is level to the understanding of the meanest. This is especially true of the gospel of Christ, to which the apostle applies it. But the word is nigh us, and Christ in that word; so that if we believe with the heart, that the promises of the Messiah are fulfilled in our Lord Jesus, and confess them with our mouth, we then have Christ with us.

Commentary on Deuteronomy 30:15-20

(Read Deuteronomy 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.
