Not carried away by feeling...

AELW 9:123

Deuternomy 12:1. These are the statutes and ordinances, etc.

"All this He commands in order that in the worship of God the people may not be carried away by its own feeling, however holy and good, but may be governed by the Word; for if man does not live without the Word even with respect to the belly, how much less does he live without the Word in the work of God and in the spirit! God wants our conscience to be certain and sure that it is pleasing to Him. This cannot be done if the conscience is led by its own feeling, but only if it relies on the Word of God. Therefore if they should worship God in a place chosen by themselves, even if they pleased themselves thereby, nevertheless they would not be sure that they were pleasing God. They were sure that they were pleasing Him only if they made offerings in a place set apart through the Word of God."

What would I lack?

AELW 9:111

Deuteronomy 10:18. He loves the sojourner, giving him food.

Look at those delightful promises of God: “Who is not partial”; likewise, “Who takes no bribe”; likewise, “He executes judgment for the fatherless and the widow”; likewise, “He loves the sojourner, giving him food and clothing” (vv. 17–18). With these words God clearly consoles all the wretched, lost, and afflicted in the whole world and draws their hearts to Himself, that they may believe in Him and trust in His goodness, as the one and only God demands. If He does not regard persons, I already have something because of which to glory, to puff up my heart, and to be proud against all the kings, princes, rich and strong men of the world. By them I am despised and deserted as poor, mean, and weak. Yet I am certain that I am regarded, sustained, and cared for by Him who is the God of gods and the Lord of lords (as Moses also teems and is magnificent with words here), the powerful one, fearful above all my despisers. What, therefore, would I lack, if some lord of a few servants despises me, while the Lord of all lords and the God of gods deems me worthy of His care?"

When want bears down upon you

AELW 9:95-96

He is a God to us and dispenses everything bountifully also when everything is most hopeless. He is willing and able to turn a rock into your drink, a desert into your food, nakedness into beautiful clothing, poverty into wealth, death into life, shame into glory, evil into good, enemies into friends—and what not? He can give and change everything from everything, everything into everything, everything from nothing, everything into nothing. Only be concerned that you believe, and where want prevails, do not break down or be concerned. And again, where abundance prevails, do not be puffed up or carelessly forget God. Whether everything is on hand or everything is lacking, cling to your God always with the same heart, knowing that He who gives plenty will give it even when want bears down upon you."
