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.And the Lord commanded us to do all these statutes,.... Some of which were designed on purpose to commemorate the wonderful deliverance out of Egypt, as particularly the passover; and all of them they were obliged in gratitude to obey, in consideration of such great favours bestowed upon them:

to fear the Lord our God, for our good always: as it is always for the good of men, temporal, spiritual, and eternal, to fear the Lord; for there is no want to them that fear him, nor will the Lord withhold good things from them; see Psalm 34:9,

that he might preserve us alive, as it is at this day; in bodily health and strength, and in the enjoyment of the good land, and all the blessings and benefits of it.
