Deut. 8:2-3. When we are led in the desert, we can be tested by God. God is sovereign. He tests us, He doesn’t tempt us. He does so, to know what is in our hearts, to purify us, to help us grow. On the way, He strengthens us by giving Manna and by helping to understand that we do not live by bread alone, but by every word that proceeds from Him.
