From Luther’s Large Catechism –
Now, since all that we possess, and, moreover, whatever, in addition, is in heaven and upon the earth, is daily given, preserved, and kept for us by God, it is readily inferred and concluded that it is our duty to love, praise, and thank Him for it without ceasing, and, in short, to serve Him with all these things, as He demands and has enjoined in the Ten Commandments.
Here we could say much if we were to expatiate, how few there are that believe this article. For we all pass over it, hear it and say it, but neither see nor consider what the words teach us. For if we believed it with the heart, we would also act accordingly, and not stalk about proudly, act defiantly, and boast as though we had life, riches, power, and honor, etc., of ourselves, so that others must fear and serve us, as is the practice of the wretched, perverse world, which is drowned in blindness, and abuses all the good things and gifts of God only for its own pride, avarice, lust, and luxury, and never once regards God, so as to thank Him or acknowledge Him as Lord and Creator.
Therefore, this article ought to humble and terrify us all, if we believed it. For we sin daily with eyes, ears, hands, body and soul, money and possessions, and with everything we have, especially those who even fight against the Word of God. Yet Christians have this advantage, that they acknowledge themselves in duty bound to serve God for all these things, and to be obedient to Him [which the world knows not how to do].
We ought, therefore, daily to practice this article, impress it upon our mind, and to remember it in all that meets our eyes, and in all good that falls to our lot, and wherever we escape from calamity or danger, that it is God who gives and does all these things, that therein we sense and see His Paternal heart and his transcendent love toward us. Thereby the heart would be warmed and kindled to be thankful, and to employ all such good things to the honor and praise of God.
