People in general like to think of themselves as “evolved”. We think that we are better than animals and each other. We think that we know what’s best for ourselves (and each other).
Ecclesiastes 3:17–18 (NLT)
 I said to myself, “In due season God will judge everyone, both good and bad, for all their deeds.”  Then I realized that God allows people to continue in their sinful ways so he can test them. That way, they can see for themselves that they are no better than animals.
This passage literally says that God allows people to continue in their sinful ways “so that He can make it clear to them.”
Even the prodigal son had this realization when he hit his low point. Jesus said, “The boy became so hungry that even the pods he was feeding the pigs looked good to him. But no one gave him anything. When he finally came to his senses, he said to himself, ‘At home even the hired men have food enough to spare, and here I am, dying of hunger!’” After squandering all his money on things that wouldn’t last, he became dependent on what people would give him.
Believers must be careful also. Paul warns us, “If you think you are standing strong, be careful, for you, too, may fall into the same sin.” And again, “Dear brothers and sisters, if another Christian is overcome by some sin, you who are godly should gently and humbly help that person back onto the right path. And be careful not to fall into the same temptation yourself.” The enemy will strike you when you are weakest…be prepared (armored up, prayed up, and immersed in God’s Word).
