James 2:20 But wilt thou know, O vain man, that faith without works is dead?
Do you consider work a bad thing? Isn't it something we all do to "earn a living"? If you were recruited and trained by a CEO wouldn't you be expected to do something to earn your reward?
Why then, is work such a bad word in relationship to our faith? Can you imagine telling your boss that you don't have to produce anything because you have been hired "by grace"? Grace got you hired alright, but you have to work if you want to be paid.
Spiritual welfare, living off of the efforts of others. That is how most Christians live out their faith. Church is the one place you can be a member and never have to do anything. It is sort of like a Greyhound bus. Get your ticket to Heaven, and "leave the driving to us."
