What was the hidden wisdom of God that was revealed about Christ?

Les explains that this wisdom had been revealed to this man: Christ was the Son of God, the Messiah, the King of Israel, but His own people rejected Him and crucified Him. It was all part of God’s eternal plan for the ages, that it had to be in order to purchase the salvation of every human being who would respond. Les notes that this wisdom was which none of the princes of this world knew—not of Israel, nor of Rome. They did not know Him as the Son of God, the Messiah of Israel. Had the leaders of Israel, the high priest, and the Pharisees known who Jesus of Nazareth really was, they would never have cried for His death. Pilate came close, saying he found no fault in this man and being warned by his wife’s dream, but he did not see it, and he also put his stamp on the crucifixion. So the princes of that then-known world did not know who Jesus of Nazareth was, and consequently they crucified Him.
