Hi Jane
I respectfully disagree with you on one point:
<< If we are needy and poor, what's the attraction to become a Christian.>>
I don't think we need to be "attracted" to Christianity, it has never been for popularity. In fact, quite the opposite is often true. We become aware of our condition and of the hope in our Saviour. We repent of our own sins and self-reliance and hand our lives over to Him in its entirety. We often need to leave even family and friends behind who are hostile to our decision. It's a passage from darknes into light and a walk through a narrow gate. It is not a club you join, although many of today's movements are trying to make just that out of it.
There are millions of strong believers around the world who are dirt poor and faith rich. In these places, the Spirit of God lives so mightily through these folks that by comparison we would all pale in shame. They are willing to be persecuted, tortured and killed for the eternal hope that is in them. Nothing about these lives seem attractive, and yet in the Kingdom of God they are the greatest saints.
No, I don't think there is anything wrong with wealth or well being per se, but it should not ever be the criteria for becoming a Christian, if it were so, then millions of believers around the globe would have missed the call into eternal life. :-)
