NOTES for Joh 12:19-36
When it comes to the Savior's earthly ministry, we understand that something unique is at issue: indeed, He alone was destined to be born and to live His earthly life as the Messiah; this was given to no one else. And yet His life became a kind of spiritual model suitable for every one of His followers. Moreover, there is simply no other model that allows one to enter the Kingdom, and apparently there cannot be, at least in our world that has undergone the fall.
This model is very simple in theory and not so simple in practice: a person must agree to part with his own life in order then to receive it again, but now as another life, in a new quality suitable for the Kingdom. The one who loves his life ("soul") as it is, in its present condition, cannot count on the Kingdom. The demand appears excessively harsh, but as we can see, this harshness is caused precisely by the specific nature of the fallen world, of which the life of each of us is a part. Even Jesus Himself, over whom original sin has no power, was not, during His earthly ministry, completely free from this specific nature: He, being fully and to the end an inhabitant of our untransformed world and part of it, became subject, if not to sin, then to death - though, of course, not in the same way as we are: death was possible for Him, not inevitable as it is for us.
And the only thing that can help us is readiness to renounce our life in its present quality, what Jesus calls "hating one's own life." It is worth remembering that in biblical language love and hatred denote not the emotional states we often mean by them, but an attitude of acceptance or nonacceptance toward that to which our will is directed. Nonacceptance of life, including first of all one's own life, in its present quality and state, and readiness to part with it for the sake of another, new life, constitute the necessary preliminary condition for beginning the path into the Kingdom: the path during which our former life will be remelted into a new one, fit for eternity.
