The messiah CANNOT DIE!
The Messiah is King forever; He is not just a temporal, worldly King.
However, He doesn't want to reign in eternity by Himself. He wants His followers with him.
How can His worldly followers follow Him forever if they are mortal? Their living in a sinful world consigns them to death.
The Messiah has provided the answer. He has taken their sin forever by suffering death for them. His suffering is the only one that will work because He is perfect.
He died only for us; He deserved none of it. His death was solely to allow our sins to be removed so we could dwell in his perfect presence for eternity.
The message was given to Israel in many, many ways but so many of them were too fixated on this world to see it. However, this message is for all peoples everywhere...Jew and Gentile...for those who will believe it.
That is what this scripture is talking about...1 Corinthians 1:18. "For the message of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God."
