Jesus is dominant in the gospels; the Spirit of Jesus in the Acts. He is the only continuous personality from first to last. He is the common denominator of the book. The first twelve chapters group about Peter, the remaining sixteen about Paul, but distinctly above both they all group about the Holy Spirit. He is the one dominant factor throughout. The first fourth of the book is fairly aflame with His presence at the center--Jerusalem. Thence out to Samaria, and through the Cornelius door to the whole outer non-Jewish world; at Antioch the new center, and thence through the uttermost parts of the Roman empire into its heart, His is the presence recognized and obeyed. He is ceaselessly guiding, empowering, inspiring, checking, controlling clear to the abrupt end. His is the one mastering personality. And everywhere His presence is a transforming presence. Nothing short of startling is the change in Peter, in the attitude of the Jerusalem thousands, in the persecutor Saul, in the spirit of these disciples, in the unprecedented and unparalleled unselfishness shown. It is revolutionary. Ah! it was meant to be so. This book is the living illustration of what Jesus meant by His teaching regarding His successor. It becomes also an acted illustration of what the personal christian life is meant to be. The Spirit's presence and the necessity of His control is deep-grained in the consciousness of the leaders in this book. Leaving the stirring scenes at the capital the eighth chapter takes us down to Samaria. Multitudes have been led to believe through the preaching of a man who has been chosen to look after the business matters of the church. Peter and John are sent down to aid the new movement. Note that their very first concern is to spend time in prayer that this great company may receive the Holy Spirit. The next chapter shifts the scene to Damascus. A man unknown save for this incident is sent as God's messenger to Saul. As he lays his hand upon this chosen man and speaks the light-giving words he instinctively adds, "and be filled with the Holy Spirit." That is not recorded as a part of what he had been told to do. But plainly this humble man of God believes that that is the essential element in Saul's preparation for his great work. In the tenth chapter the Holy Spirit's action with Cornelius completely upsets the life-long, rock-rooted ideas of these intensely national, and intensely exclusive Jews. Yet it is accepted as final. With what quaint simplicity does the thirteenth chapter tell of the Holy Spirit's initiation of those great missionary journeys of Paul from the new center of world evangelization? "the Holy Spirit said, etc." And how like it is the language of James in delivering the judgment of the first church council:--"it seemed good to the Holy Spirit and to us."
