Lol don't you know that you're just supposed to WATCH the world suffer so that you can say 'see? Armageddon is close, it can't get worse!'
it's distinctly non witnessy of you!! Otherwise, the only ties habitat for humanity has with Babylon the great is that jimmy carter and his wife are very Christian. I don't think this charity is directly tied to a religion tho, at least not officially. I don't think they can indict you of anything directly.
Go help people!!
