Alex, I find your correspondence rather confusing. Perhaps I'm wasting my time with it and should go on to more valuable matters; however, for your sake, with hopes of alerting you to need of understanding, I reply (I'm being sincere and not facetious).
You initially wrote: “After all you said money is evil, if it is evil - why do you need money. You should give away your products for free, so you can practice what you preach.”
I corrected you and asked you to produce evidence to that charge, but you didn't acknowledge your error or apologize and you provided no substance to back your accusation. Why not? Don't you believe me? Am I a liar, Alex, or do you think I'm just a fool you can toy with?
Instead, you shifted your position and replied, “The only reason I emailed you because Christians lead other Christians who are gifted in business or the professional world to feel guilty for doing exploits.”
I'm asking you to be honest and decent. I have not condemned or criticized anyone, Christian or otherwise, for being gifted or involved in business or various other occupations. You likely need to read my paper a few times in order to understand it somewhat before accusing me without cause, don't you think?
Then you state, “If we have no Christian billionaires like David Green or Rich Devos, then we will have no one to fund the gospel.” You certainly didn't get that notion from the Bible, Alex. You err in worship of mammon when you ought to have faith and worship God, as you assume you do. Here's how Jesus sent forth His disciples, contrary to your notion that mammon is needed to finance God to destroy worship of itself:
“Carry neither purse nor bag nor sandals. And greet no one by the way” (Luke 10:4 MKJV).
“And He said to them, When I sent you without purse and wallet and sandals, did you lack anything? And they said, Nothing” (Luke 22:35 MKJV).
Mark 6:7-9 MKJV
(7) And He called the Twelve and began to send them out by two and two. And He gave them authority over unclean spirits,
(8) and commanded them that they take nothing in the way, except only a staff; no bag, no bread, no copper in the belt,
(9) but tying on sandals, and not to put on two tunics.
God doesn't need your billionaires, Alex, and He has not appointed the rich of this world to empower Him. Which of the prophets, apostles or saints depended on wealthy people to finance them? Consider that God even used ravens and a greatly impoverished widow to provide for Elijah (1 Kings 17).
Yes, occasionally there were wealthy people who followed and surely gave to Him and to His disciples, but they were never a godly ministry's source or enabling to do the work of God. In that, you greatly err, worshiping mammon instead of God:
“But if your eye is evil, your whole body shall be full of darkness. If therefore the light that is in you is darkness, how great is that darkness! No one can serve two masters. For either he will hate the one and love the other, or else he will hold to the one and despise the other. You cannot serve God and mammon” (Matthew 6:23-24 MKJV).
