A.T. Robertson Commentary 1 Corinthians 1:25

"Because the foolishness of God is wiser than men; and the weakness of God is stronger than men." — 1 Corinthians 1:25 (ASV)

The foolishness of God (το μωρον του θεου). Abstract neuter singular with the article, the foolish act of God (the Cross as regarded by the world).

Wiser than men (σοφωτερον των ανθρωπων). Condensed comparison, wiser than the wisdom of men. Common Greek idiom (Matthew 5:20; John 5:36) and quite forcible, brushes all men aside.

The weakness of God (το ασθενες του θεου). Same idiom here,

the weak act of God , as men think,

is stronger (ισχυροτερον). The Cross seemed God's defeat. It is conquering the world and is the mightiest force on earth.
