Deu 8:11-18 “Take care lest you forget the LORD your God by not keeping his commandments and his rules and his statutes, which I command you today, lest, when you have eaten and are full and have built good houses and live in them, and when your herds and flocks multiply and your silver and gold is multiplied and all that you have is multiplied, then your heart be lifted up, and you forget the LORD your God, who brought you out of the land of Egypt, out of the house of slavery, who led you through the great and terrifying wilderness, with its fiery serpents and scorpions and thirsty ground where there was no water, who brought you water out of the flinty rock, who fed you in the wilderness with manna that your fathers did not know, that he might humble you and test you, to do you good in the end. Beware lest you say in your heart, ‘My power and the might of my hand have gotten me this wealth.’ You shall remember the LORD your God, for it is he who gives you power to get wealth, that he may confirm his covenant that he swore to your fathers, as it is this day. And if you forget the LORD your God and go after other gods and serve them and worship them, I solemnly warn you today that you shall surely perish. Like the nations that the LORD makes to perish before you, so shall you perish, because you would not obey the voice of the LORD your God.
Proverbs 1:32 For the simple are killed by their turning away, and the complacency of fools destroys them;
Proverbs 30:9 lest I be full and deny you and say, “Who is the LORD?” or lest I be poor and steal and profane the name of my God.
Psalms 106:21 They forgot God, their Savior, who had done great things in Egypt,
Hosea 13:5-6 It was I who knew you in the wilderness, in the land of drought; but when they had grazed, they became full, they were filled, and their heart was lifted up; therefore they forgot me
Jeremiah 2:31 And you, O generation, behold the word of the LORD. Have I been a wilderness to Israel, or a land of thick darkness? Why then do my people say, ‘We are free, we will come no more to you’?
1 Corinthians 4:7 For who sees anything different in you? What do you have that you did not receive? If then you received it, why do you boast as if you did not receive it?
Psalms 127:1-2 Unless the LORD builds the house, those who build it labor in vain. Unless the LORD watches over the city, the watchman stays awake in vain. It is in vain that you rise up early and go late to rest, eating the bread of anxious toil; for he gives to his beloved sleep.
When everything is fine and our lives are filled with abundance, it is not hard to have our hearts lifted up. We can easily forget the LORD Himself and forget it was all His work on our behalf. In times of abundance, it is easy to forget the LORD, or to at least no longer seek Him with the urgency we once had. We often think highly of our own hard work and brilliance. Yet we must see that God gives us the body, the brain, and the talent. It is all of God. His plan is that it would ultimately further His eternal purpose. Therefore, we have no right to use our material blessing to further selfish purposes; instead, we use our resources to advance His kingdom. (Guzik)
Moses directs to the duty of a prosperous condition. Let them always remember their Benefactor. In everything we must give thanks. Moses arms them against the temptations of a prosperous condition. When men possess large estates, or are engaged in profitable business, they find the temptation to pride, forgetfulness of God, and carnal-mindedness, very strong; and they are anxious and troubled about many things. In this the believing poor have the advantage; they more easily perceive their supplies coming from the Lord in answer to the prayer of faith; and, strange as it may seem, they find less difficulty in simply trusting him for daily bread. They taste a sweetness therein, which is generally unknown to the rich, while they are also freed from many of their temptations. Forget not God’s former dealings with thee. Here is the great secret of Divine Providence. Infinite wisdom and goodness are the source of all the changes and trials believers experience. Israel had many bitter trials, but it was to do them good. Pride is natural to the human heart. Would one suppose that such a people, after their slavery at the brick-kilns, should need the thorns of the wilderness to humble them? But such is man! And they were proved that they might be humbled. None of us live a single week without giving proofs of our weakness, folly, and depravity. To broken-hearted souls alone the Saviour is precious indeed. Nothing can render the most suitable outward and inward trials effectual, but the power of the Spirit of God. See here how God’s giving and our getting are reconciled, and apply it to spiritual wealth. All God’s gifts are in pursuance of his promises. Moses repeats the warning he had often given of the fatal consequences of forsaking God. Those who follow others in sin, will follow them to destruction. If we do as sinners do, we must expect to fare as sinners fare. (Henry)
