(A special psalm by David for the music leader. He wrote this when Doeg from Edom went to Saul and said, "David has gone to Ahimelech's house.") You people may be strong and brag about your sins, but God can be trusted day after day.
If we please God, he will make us wise, understanding, and happy. But if we sin, God will make us struggle for a living, then he will give all we own to someone who pleases him. This makes no more sense than chasing the wind.
For example, some people don't have friends or family. But they are never satisfied with what they own, and they never stop working to get more. They should ask themselves, "Why am I always working to have more? Who will get what I leave behind?" What a senseless and miserable life!
You cannot be the slave of two masters! You will like one more than the other or be more loyal to one than the other. You cannot serve both God and money.
