8:1-9 Obedience must be, 1. Careful, observe to do; 2. Universal, to do all the commandments; and 3. From a good principle, with a regard to God as the Lord, and their God, and with a holy fear of him. To engage them to this obedience. Moses directs them to look back. It is good to remember all the ways, both of God's providence and grace, by which he has led us through this wilderness, that we may cheerfully serve him and trust in him. They must remember the straits they were sometimes brought into, for mortifying their pride, and manifesting their perverseness; to prove them, that they and others might know all that was in their heart, and that all might see that God chose them, not for any thing in them which might recommend them to his favour. They must remember the miraculous supplies of food and raiment granted them. Let none of God's children distrust their Father, nor take any sinful course for the supply of their necessities. Some way or other, God will provide for them in the way of duty and honest diligence, and verily they shall be fed. It may be applied spiritually; the word of God is the food of the soul. Christ is the word of God; by him we live. They must also remember the rebukes they had been under, and not without need. This use we should make of all our afflictions; by them let us be quickened to our duty. Moses also directs them to look forward to Canaan. Look which way we will, both to look back and to look forward, to Canaan. Look which way we will, both to look back and to look forward will furnish us with arguments for obedience. Moses saw in that land a type of the better country. The gospel church is the New Testament Canaan, watered with the Spirit in his gifts and graces, planted with trees of righteousness, bearing fruits of righteousness. Heaven is the good land, in which nothing is wanting, and where is fulness of joy.

2, 3. thou shalt remember all the way which the Lord thy God led thee these forty years in the wilderness—The recapitulation of all their checkered experience during that long period was designed to awaken lively impressions of the goodness of God. First, Moses showed them the object of their protracted wanderings and varied hardships. These were trials of their obedience as well as chastisements for sin. Indeed, the discovery of their infidelity, inconstancy, and their rebellions and perverseness which this varied discipline brought to light, was of eminently practical use to the Israelites themselves, as it has been to the church in all subsequent ages. Next, he enlarged on the goodness of God to them, while reduced to the last extremities of despair, in the miraculous provision which, without anxiety or labor, was made for their daily support (see on [121]Ex 16:4). Possessing no nutritious properties inherent in it, this contributed to their sustenance, as indeed all food does (Mt 4:4) solely through the ordinance and blessing of God. This remark is applicable to the means of spiritual as well as natural life.
