This quote is from a collection of text studies arranged for the church year and published in the 1850s and 1860s. They were compiled from the Harmony of the Gospels by the Lutheran theologians Martin Chemnitz, Polycarp Leyser, and Johann Gerhard, published from 1593 to 1652. This section is on the Gospel for the Seventh Sunday after Trinity, Mark 8:1–9, which is talking about the disciples’ lack of trust that Jesus could provide food for 4,000 as he had for the 5,000.
Let us also recognize our own lack of trust, which frequently tends to plague us in household affairs, when perhaps God grants more children and entrusts a larger family to us for their maintenance. Then these kinds of words are commonly heard: Where will I get enough bread to satisfy this bunch? Where will I get the money and the means, so that in such a precarious situation I will be able to take care of me and my own? But trust in God—He, who gives fodder for the cattle and for the young ravens, who call on him (Ps 147:9)—He will also nourish you. Say to your hearts: Why do you torment yourself with useless worries? God is your Creator; he has given you your body and soul; he will also give you food.
