For Jews demand signs and Greeks look for wisdom, but we proclaim Christ crucified, a stumbling block to Jews and foolishness to Gentiles, but to those who are called, Jews and Greeks alike, Christ the power of God and the wisdom of God. For the foolishness of God is wiser than human wisdom, and the weakness of God is stronger than human strength. (1 Cor 1:17-25)

To proclaim Christ crucified, the power of God and the wisdom of God. The Cross is the absolute foolishness of God. That God would want to be one with all the losers of this world. Yet the preaching of the Cross is where wisdom is found.
