For the Church as such this coming of the Spirit meant the entrance of the work of the Incarnation upon a new phase of its action. We may, I suppose, think of the work of our Lord during the years of His Ministry as intensive. It was the work of preparing the men to whom was to be committed the commission to preach the Kingdom of God. They had been chosen to be with Him, and their training had been essentially an experience of Him, an experience which was to be the essence of their Gospel and which their mission was to interpret to the world. "Who is this Jesus of Nazareth Whom ye preach? What does He mean?" was to be the question that they would have to answer in the coming years; and they would have to answer it to all sorts of men; to Jews who would find this conception of a suffering and rejected Messiah "a stumbling-block"; to the Greeks who would find "Jesus and the resurrection" "foolishness"; to all races of men who would have to be persuaded to leave their ancestral religions and revolutionise their lives, and before they would do so would wish to know what was the true meaning of Christ in whose name their whole past was challenged. As we watch the perplexity, the bewilderment, of these Apostles in the face of the collapse of all their hopes on the first Good Friday, as we see them struggling with the fact of the Resurrection, and attempting to adjust their lives to that; and then listen to their preaching and follow their action in the days succeeding Pentecost, we have brought home to us the nature of the action of the Holy Spirit when He came to them as the Spirit of Jesus to enable them to carry on the work that Jesus had committed to them.
