But those who want to be rich fall into temptation, a trap, and many foolish and harmful desires, which plunge people into ruin and destruction. 1 Timothy 6:9
Often wealth once you have it can be less of a blessing than you thought it would be, especially when you get it through less than positive means.
There is a story on HigherPraise.com of a family who, when they won the lottery, found that money can have a lot of negative consequences:
When the McGugarts of New York won the Irish Sweepstakes, they were happy. Pop was a steamfitter. Johnny, twenty-six, loaded crates on docks. Tim was going to night school. Pop split the million with his sons. They all said the money wouldn't change their plans. A year later, the million wasn't gone; it was bent. The boys weren't speaking to Pop, or each other. Johnny was chasing expensive race horses; Tim was catching up with expensive girls. Mom accused Pop of hiding his poke from her. Within two years, all of them were in court for nonpayment of income taxes. “It's the Devil's own money,” Mom said. Both boys were studying hard to become alcoholics.
If God has blessed you with great wealth, keep in mind that it is only temporary, and that everything we have is God's to begin with. If the money becomes all consuming, and you feel like you would do anything to keep it, remember 1st Timothy 6:10:
For the love of money is a root of all kinds of evil, and by craving it, some have wandered away from the faith and pierced themselves with many pains.
Remember what's important – faith in Jesus Christ and the salvation he gave us when he died on the cross. Everything else is but dust in the wind.
