He knows it’s best for some people to have more than others, too. Sometimes, some very dangerous sins can sneak into our hearts when we think about what others have. The Lord made the tenth commandment “though shalt not covet” for a reason.
This is not just about not wanting others’ stuff, though. If it was, I’d have mentioned David and Bathsheba again. Indeed, people can sometimes be very indignant about others’ sin in coveting, even though they are doing the exact same thing.
But, not only should someone who is rich not covet what little others have, those who have little should not be upset that others have more. It’s about accepting them as God would. They may or may not use their stuff wisely. But, God will deal with that. He wants us to love them, because He does. His mercies are everlasting.
Since He loves everyone, He wants us to, also. He wants us to look beyond things, and learn to rely on Him totally.
If someone has a lot of stuff and is selfish with it, the correct response should never be anger. The correct attitude should be pity, sadness, and prayer for their souls. That is just how God feels, as He lovingly tries to win the lost, and to get those who are saved but unwise to dedicatee their many goods to Him. That doesn’t mean they have to give them all away. But, it does mean they should be generous, not just tithing (as all of us should) but actively giving to missions and other programs that honor God, and so on. Not all works honor Him, of course – a pastor doesn’t need a million dollar mansion, that money can easily go toward a modest house for himself and a lot more toward missions or some other project. However, it’s up to God to judge peoples’ hearts.
