1 Corinthians 3:18-20
.19 For the wisdom of this world is foolishness in the sight of God. For it is written: “He is the one who catches the wise by their craftiness”
Nowhere does this scripture talk about God being foolish; that is a perversion of the truth being deployed by you.
"It is the Wisdom of the world that is foolishness with God", So the thinking of the world is the issue.
John made the point 1 John 2:15-17
"Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him. For all that is in the world—the desires of the flesh and the desires of the eyes and pride in possessions—is not from the Father but is from the world. And the world is passing away along with its desires, but whoever does the will of God abides forever.
So the thinking of the world is not the thinking of God.
Later John also tells us us
"We know that we are of God, and the whole world lies under the sway of the wicked one (1 John 5:19)."
So if the whole world lies in the power of the wicked one, and it is the wisdom of the world that is being challenged, that does not make God foolish, but those who adopt the thinking of the world.
