The cross is at the center of Christian theology. Paul, in Galatians 6:14 said, "But God forbid tat I should glory, save in the cross of our Lord Jesus Christ, but whom the world is crucified unto me, and I unto the world." Jesus, at this point in His earthly like and humanity was on His way to where His enemies were awaiting Him. He knew that He was going up to Jerusalem to suffer and die for the sins of the world. And, that He would rise from the dead on the third day.
