Messianic expectations in Gospel times assumed that the Messiah would lead a movement of His supporters that would end in His complete victory over all enemies and in the restoration of an independent Jewish state, which was to become the foundation of the messianic Kingdom.
It was assumed that God would intervene and support His Chosen One if anything went wrong. Of course, this meant a completely real, physical war, during which the Messiah was also in real danger of dying, but it was assumed that God would not allow that. Of course, the Messiah could suffer in some way during the messianic war, but He could not die, because then His mission would remain unfulfilled. Jesus' disciples shared these expectations too; after all, they were people of their time.
It is no accident that in response to the Savior's words about His death, Peter begins to argue with Him. He was sure that the Teacher's death meant the end, the failure, the collapse not only of their own expectations but also of God's plan, and that was already completely impossible. Jesus Himself had just confirmed that He was the Messiah, so He could not die; that simply could not be. Yet He speaks about His death as something not only possible but directly inevitable.
How could all this be understood and brought together? Jesus, of course, knows perfectly well that all those truths about His death and resurrection that seem self-evident to us today in fact do not fit at all into the consciousness of fallen humanity. They seem self-evident to us today only because they are widely accepted and therefore familiar. That is why He begins the conversation about what true life is and what it is like. Without understanding these basic things, without grasping them, a conversation about death and resurrection - not only of the Messiah but of any person at all - becomes quite meaningless.
Jesus reminds His disciples that life, the "soul," is not the property of an individual person, not his possession. Life is given to a person by God as the stream into which the person is immersed and in which he remains, while that stream also dwells mysteriously within the person. The body is only the outer and passing shell of the stream of life, but to fallen humanity it seems as though the person preserves life in his own body as in a vessel, and if the vessel is broken, life will disappear, spill out, and run away like water into sand.
In reality, death and the destruction of the body are only a transformation, provided, of course, that a person is not truly trying to hold back the stream of life, stop it, and seal it inside his own physical body. In that case, in trying to save his life, or "soul," a person truly loses everything. But if he gives up such attempts, he can receive the life of the Kingdom in all the fullness available to him, like that inexhaustible river of living water of which the prophets spoke.
