The suffering begins where?

Jesus is the suffering servant Son right from Bethlehem. We must think of the work of the cross, therefore, as beginning immediately with his birth, increasing in his growth into manhood, and deepening in intensity as he entered his public ministry. His whole life is his passion, for his very incarnation as union of God and man is an intervention into the enmity between God and mankind. Jesus Christ steps into the situation where God judges mankind and where mankind contradicts God. He steps in not as a third party but as the God who judges man, and steps into the place of man who sins against God and is judged by God. The very union of God and man, and the living out of that union from day to day in the realisation of God’s gracious election, intensified that state of enmity, making it ultimate, that is, making it the eschaton.—T. F. Torrance, Incarnation: The Person and Life of Christ, 110–11
