Christian business owners carry a guilt complex. You make money, and immediately feel like you need to explain it away. "Well, we're giving 10% to missions." "We're trying to be good stewards." "It's not about the money." 

But here's what you're actually saying: "Making profit feels wrong, so let me show that I'm one of the good ones."

If you feel guilty about making money, then you've accepted the premise that profit is morally suspect. That success needs justification. That if you're doing well, you must be doing something wrong—or at least, something morally neutral that needs to be redeemed by doing something _actually_ good with it.

Serve your customers. Make good products. Create good jobs. And thank the Lord as you steward 

your business under God's provisional blessing. Stop apologizing for success.
