20 When your children ask you in time to come, "What is the meaning of the decrees and the statutes and the ordinances that the Lord our God has commanded you?" 21 then you shall say to your children, "We were Pharaoh's slaves in Egypt, but the Lord brought us out of Egypt with a mighty hand. 22 The Lord displayed before our eyes great and awesome signs and wonders against Egypt, against Pharaoh and all his household. 23 He brought us out from there in order to bring us in, to give us the land that he promised on oath to our ancestors. 24 Then the Lord commanded us to observe all these statutes, to fear the Lord our God, for our lasting good, so as to keep us alive, as is now the case. 25 If we diligently observe this entire commandment before the Lord our God, as he has commanded us, we will be in the right."
Matthew Henry's Commentary on Deuteronomy 6:20-25
Commentary on Deuteronomy 6:17-25
(Read Deuteronomy 6:17-25)
Moses gives charge to keep God's commandments. Negligence will ruin us; but we cannot be saved without diligence. It is our interest, as well as our duty, to be religious. It will be our life. Godliness has the promise of the continuance and comfort of the life that now is, as far as it is for God's glory. It will be our righteousness. It is only through the Mediator we can be righteous before God. The knowledge of the spirituality and excellency of the holy law of God, is suited to show sinful man his need of a Saviour, and to prepare his heart to welcome a free salvation. The gospel honours the law, not only in the perfect obedience of the Son of God, the Lord Jesus Christ; but in that it is a plan for bringing back apostate rebels and enemies, by repentance, faith, forgiveness, and renewing grace, to love God above all things, even in this world; and in the world above, to love him perfectly, even as angels love him.
