Are you a wasteful spender? Hopefully none of us match the prodigal son who showed extreme disregard for stewardship by demanding an early inheritance and squandering it on partying and prostitutes. (Luke 15:11-32)
However, while being respectable Christians, we can be careless and wasteful in spending money on items which are useless, of low quality, or outside the scope of our financial priorities.
There's no list of "sinful" luxury items that applies to everybody. One man may be sinning to buy a $10 Music CD because he has not yet met his primary obligation is to provide food and clothing for his family. (
1 Timothy 5:8) Another man may buy a $40,000 new car if he has provided well for his family, if he has tithed faithfully to God, and he is viewing the car as a means and not an end.
Impulsive spending and spending beyond the bounds of your income is a sinful addiction like gambling or smoking. If a passion to buy things controls you, Christ is not your master, and you need to repent.
1 Timothy 5:8 "But if anyone does not provide for his own, and especially for those of his household, he has denied the faith and is worse than an unbeliever."
