20 "In the future your children will ask you, 'What is the meaning of these laws, decrees, and regulations that the Lord our God has commanded us to obey?' 21 "Then you must tell them, 'We were Pharaoh's slaves in Egypt, but the Lord brought us out of Egypt with his strong hand. 22 The Lord did miraculous signs and wonders before our eyes, dealing terrifying blows against Egypt and Pharaoh and all his people. 23 He brought us out of Egypt so he could give us this land he had sworn to give our ancestors. 24 And the Lord our God commanded us to obey all these decrees and to fear him so he can continue to bless us and preserve our lives, as he has done to this day. 25 For we will be counted as righteous when we obey all the commands the Lord our God has given us.'
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.
