Mischief blinds good judgment as we see when Moses stayed away from camp too long with the Lord, he returned to find Aaron taken by the mischief of the people as he said he gathered their gold and cast it into the fire and a calf came out. Really? (Exodus 32:21-24). And Moses said unto Aaron, What did this people unto thee, that thou hast brought so great a sin upon them?And Aaron said, Let not the anger of my lord wax hot: thou knowest the people, that they are set on mischief. For they said unto me, Make us gods, which shall go before us: for as for this Moses, the man that brought us up out of the land of Egypt, we wot not what is become of him. And I said unto them, Whosoever hath any gold, let them break it off. So they gave it me: then I cast it into the fire, and there came out this calf.
When a persons mindset is not on the things of God all sorts of mischief can come about, and God alows this as man has free will. You can always be sure if one is mischievious that it won’t be long and it will return upon him. (Proverbs 11:27,30,31). He that diligently seeketh good procureth favour: but he that seeketh mischief, it shall come unto him. The fruit of the righteous is a tree of life; and he that winneth souls is wise. Behold, the righteous shall be recompensed in the earth: much more the wicked and the sinner.
As a Christian we know any mischief comes not from above, but from the devil himself. We see this from the lesson of El’-y-mas the sorcerer who tried to turn the deputy from his faith and Saul did not hold back by telling him of the slyness he thought he would get away with. (Acts 13:8-12). But Elymas the sorcerer (for so is his name by interpretation) withstood them, seeking to turn away the deputy from the faith. Then Saul, (who also is called Paul,) filled with the Holy Ghost, set his eyes on him.And said, O full of all subtilty and all mischief, thou child of the devil, thou enemy of all righteousness, wilt thou not cease to pervert the right ways of the Lord? And now, behold, the hand of the Lord is upon thee, and thou shalt be blind, not seeing the sun for a season. And immediately there fell on him a mist and a darkness; and he went about seeking some to lead him by the hand.Then the deputy, when he saw what was done, believed, being astonished at the doctrine of the Lord.
