The class focused on 4:19:
And my God will meet all your needs according to the riches of his glory in Christ Jesus. (NIV)
The teacher asserted that this verse was used to justify a "prosperity gospel," in that people asserted that "all your needs" was the same as "all your wants." I never really thought of this verse in terms of a prosperity gospel, so I was arriving at it with what I thought were neutral biases - and wanted to find out more about what the words being used were, since translations seem odd to me when they're so easily misapplied.
