The readings for Tuesday in Holy Week include this from 1 Corinthians 1:18-25,
The message about the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God. For it is written,
"I will destroy the wisdom of the wise,
and the discernment of the discerning I will thwart."
Where is the one who is wise? Where is the scribe? Where is the debater of this age? Has not God made foolish the wisdom of the world? For since, in the wisdom of God, the world did not know God through wisdom, God decided, through the foolishness of our proclamation, to save those who believe. For Jews demand signs and Greeks desire wisdom, but we proclaim Christ crucified, a stumbling block to Jews and foolishness to Gentiles, but to those who are the called, both Jews and Greeks, Christ the power of God and the wisdom of God. For God's foolishness is wiser than human wisdom, and God's weakness is stronger than human strength.
We claim the foolish message that God showed power through powerlessness, and we find it to be so very true. Max Lucado offers a multimedia reminder of Christ's work for us on the cross
at a website deigned to sell his book, He Chose the Nails. The multimedia is a little long (3 minutes or so) but worth a look and the book is available for checkout from King of Peace's library in it's full form and a shorter version made to share with a friend.
