I should point out that every one of us will likely end up flat on our backs in the proverbial desert simply because we didn’t know what God was doing in the situation and we guessed wrong. Ephesians does say that we are to understand what the will of God is (using Scripture) but that is not always an easy task. Our sin natures fight us on this.
So please please please, do not go blaming people who are proverbially on their backs in the desert for their hardships and calamity. I do not mean that as an authoritative preachy voice: it is a personal plea from the bottom of my heart. Please don’t do this. People have done this to me and it has hurt terribly.
