“If He sees that wealth will not profit your soul, than He will pay you another way. "Let your conversation be without covetousness; and be content with such things as ye have: for he has said, I will never leave thee nor forsake you" Hebrews 13:5.
If God gives you wealth but later asks you to part with it for His name's sake, He hands you His bond along with His request to recover the loss with "a hundredfold" advantage in this life, besides eternal life in the world to come Matthew 19:29. Only a fool will part with God's promises for any security the devil can give.
A heavy curse always cleaves to unrighteous gain. "The curse of the Lord is in the house of the wicked" Proverbs 3:33 but "in the house of the righteous is much treasure" Proverbs 15:6. You may visit a righteous man's house and find no money but you are sure to find a treasure. Yet in the wicked man's house there may be much gold and silver but never treasure-- the curse of God eats up all his gains. God's fork follows the wicked man's rake.
The ungodly bring shame into their houses, "for the stone shall cry out of the wall, and the beam out of the timber shall answer it" Habakkuk 2:11. And what man who cherishes his life would live in a haunted house like this, even for tons of gold? The cry of his unrighteousness follows him into every room of the house and echoes until he can hear the stones and beams groaning under the weight of sin that put them there.
This sin is so hateful to the righteous God that not only the man who gathers unrighteous gain, but also the instruments he uses to advance his project, are cursed. Thus the servant who cooperates with his master's fraud collects God's wages too. "I will punish all those that leap on the threshold, which fill their masters' houses with violence and deceit" Zephaniah 1:9.”Quoted material from, ”The Christian in Complete Armour Daily Readings in Spiritual Warfare” by Gurnall and James S Bell. http://www.moodypublishers.com/pub_productDetail.aspx?id=41823&pid=53617
