Last week, I subbed in the older adult Sunday school class. The lesson was from the David C. Cook quarterly material...it focused on "true prosperity" by examining Psalm 1. I opened the class with the statement, "This could be a dangerous lesson."
I had prepped for the class by reviewing the material, verses and questions. Nowhere did the literature mention Jesus or the Gospel. It made a lot of great points about obedience bringing rewards, but it just seemed dangerous to me to talk prosperity without putting it within the light of the Gospel.
We begin to grasp what prosperity is when we are able to say with Paul,
"But whatever gain I had, I counted as loss for the sake of Christ. Indeed, I count everything as loss because of the surpassing worth of knowing Christ Jesus my Lord. For his sake I have suffered the loss of all things and count them as rubbish, in order that I may gain Christ and be found in him, not having a righteousness of my own that comes from the law, but that which comes through faith in Christ, the righteousness from God that depends on faith—" Philippians 3:7-9
It's likely that we are not totally there yet and are in need of the light of the Gospel.
