Most of us have heard that having lots of money cannot buy love or bring happiness. Since I've never been mega-wealthy, I will trust God on this one.
Most people are trying to build financial security, but it's also common for those who succeed to encounter frustration and disappointment. Ecclesiastes 5:10-12 gives us this divine insight, "Whoever loves money never has enough; whoever loves wealth is never satisfied with their income. This too is meaningless. As goods increase, so do those who consume them, and what benefit are they to the owners except to feast their eyes on them? The sleep of a laboring man is sweet, whether he eats little or much, but the abundance of the rich will not allow him to sleep."
We notice this passage begins with someone who loves money as there is a difference between enjoying wealth and wealth becoming an idol that is worshiped.
