That’s precisely the problem. It’s upbeat because they deny the doctrine of redemptive suffering. To so-called “Prosperity Gospel” preachers, poverty and suffering happen because you’re not faithful enough. They only preach the part of the Gospel where there is happiness and peace and no suffering and strife. Jesus said, I come not to bring peace but a sword. You won’t hear that mentioned by Joyce Meyer.
Please stop wasting time listening to Joyce Meyer and instead read
Salvifici doloris, a remarkable document, short in length, written by Saint John Paul the Great, that explains Catholic teaching and why it is incompatible with the bogus “Prosperity Gospel” doctrines.
