S – Yet to those who are called, both Jews and Greeks, Christ is the power of God and the wisdom of God, ²⁵ because God’s foolishness is wiser than human wisdom, and God’s weakness is stronger than human strength. 

1 Corinthians 1:24–25 CSB

O – Commentary:  

called— The same class as the “us which are (being) saved” (1 Co 1:18); the elect, who have obeyed the call; called effectually (Ro 8:28, 30).

Christ—“Crucified” is not here added, because when the offense of the cross is overcome, “Christ” is received in all His relations, not only in His cross, but in His life and His future kingdom.

power—so meeting all the reasonable requirements of the Jews who sought “a sign.” The cross (the death of a slave), which to the Jews (looking for a temporal Messiah) was a “stumbling-block,” is really “the power of God” to the salvation of all who believe.

wisdom of God—so really exhibiting, and in the highest degree (if they would but see it), that which the Greeks sought after—wisdom (Col 2:3).

foolishness of God—that is, God’s plan of salvation which men deem “foolishness.”

weakness of God—Christ “crucified through weakness” (2 Co 13:4, the great stumbling-block of the Jews), yet “living by the power of God.” So He perfects strength out of the weakness of His servants (1 Co 2:3; 2 Co 12:9).

Commentary Critical and Explanatory on the Whole Bible,

A – Jews sought a sign and power and Gentiles wisdom.  And we can still do this today.  We want to see what God can do and want the wisdom to validate how special we are.  Christ was killed in humility and simplicity yet He possessed all the glory and wisdom.  When we walk like Christ, we will confound others in our “approach” but they will not be able to deny His substance.
