1 Corinthians 1:22

For the Jews require a sign, and the Greeks seek after wisdom (KJV)

Then: Paul's talking about culture models. Throughout the Old Testament Jews expected truths to be revealed with a miraculous events. That proved their validity. The Greeks expected to verify knowledge through logic, reasoning, and acceptance of teachings from great philosophers. Truth in any other form could not confound and reveal. God ordered his plan in his own fashion - through the person and actions of his incarnate son. The confirmation of Truth came through the presence of the Holy Spirit - not from signs. Not from worldly wisdom.

Now: Barriers and preconcepts make believing in God difficult. He has to break through everything that seems normal in a human's mind and show there's more. Life is fuller, greater, and more inclusive than anyone could have imagined. Those who sing can really sing. Those who dance can really dance. Those who laugh can really laugh. For God is -- loving and forgiving, inviting and confirming. Accept him. Accept life. Paul tells us about God's message, valid since the beginning of creation. The Holy Spirit speaks it in our hearts.
