There's a lot of debate in Christian circles (and non-Christian circles, for that matter) about Christians and money. For this reason, I wrote an article (published February 12) on the subject. I encourage you to read it, and comment in the discussion forum. In the meantime, I want to add a few personal remarks about this sensitive issue (since the blog is more for personal commentary).
Is it Wrong for Christians to Make Lots of Money?
Answer: NO. It is perfectly acceptable for Christians to earn money and to even get rich. The problem comes when that becomes the primary goal of the Christian. The writer of Ecclesiastes warns that he "who loves silver shall not be satisfied with silver; nor he that loves abundance with increase" (Ecclesiastes 5:10).
What's more, as was said in the article, if you are seeking "treasures on earth" as opposed to "treasures in heaven," your priorities are out of whack. Jesus tells us to seek the kingdom of God first and foremost.
How Much is Too Much?
Answer: You can earn as much as God guides you to earn and blesses you with. Money is a tool. As long as you see it as a tool - meaning that it is a MEANS to an end, and NOT an end of itself - then you're on the right track to keeping things in balance. So, what is the "end" that you are pursuing?
Commit your heart and efforts to the Lord, and follow His leading. Make God #1 in your life, and then you'll find that money and everything else will fall into place.
