It's like saying an engine is all you need to run a car. You need the fuel, too. The fuel is "works". Otherwise, the motor is useless.
"That seems to be contradicted by numerous passages in the Bible."
Really? Your Bible doesn't have Jesus acquiring wealth and then sitting on his ass, rather than helping people, because Jesus 'had faith and that was enough'?
Yeah - mine doesn't either.
I'm not a big fan of a religion that rewards sloth over action.
