I just got the "Come Be My Follower" book and am shocked at their illustration on page 186. Maybe I'm more shocked that at one time I would have accepted this warped reasoning.
First they quote Jesus at Matt. 7:21-23: "'Lord, Lord, did we not...perform many powerful works in your name?' And yet then I will confess to them: I never knew you! Get away from me, you workers of lawlessness."
para 11: Many today who call themselves Christians might find those word puzzling. Why would Jesus direct such strong words to people who have been performing "many powerful works" in his name? The churches of Christendom have sponsored charities, aided the poor, built hospitals and schools, and performed many other works. To see why they have earned Jesus' anger, consider an illustration:
para 12: A father and mother need to go on a trip. They cannot take their children along, so they hire a babysitter. Their instructions to her are simple: "Take care of our children. Feed them, make sure they are clean, and keep them from harm." When the parents return, though, they are shocked to see that their children are famished. They are dirty, sickly, and miserable. They are crying for the babysitter's attention, but their cries go unheeded. Why? She is up on a ladder, washing the windows. Furious, the parents demand an explanation. The sitter replies: "Look at all that I did! Aren't the windows clean? I made repairs to the house too, all for you!" Would the parents feel better? Hardly! They never asked her to do those jobs; they just wanted their children cared for. her refusal to heed their instructions would infuriate them.
They admit that Christendom is trying to take care of the physical needs of their people and somehow this is going to incur God's wrath. But the Watchtower does very little in a material way (unless they can get newspaper publicity), but God loves them because they feed people spiritually. See James 2:14-17.
