A little group of men were climbing the winding path that led up Olivet's slope. The Master was in the midst, and the others before and behind, where they could hear His voice. For they were talking together as they walked along. That is to say, He was talking, and they were listening, with an occasional question. They went on until they were over against where little Bethany nestles in among the blue hills. There they stood a little while, still talking together earnestly.
It was their last talk together. And there were two things the Master was saying. Those two things came with all the tender emphasis of a last message. They were to go on an errand to the world; a lifelong errand, and to the whole world. That was being burned in. But they weren't to start on the errand until the Holy Spirit had come upon them. The errand and the Spirit's presence were coupled together. That was to be their errand. And He was to be their life-power as they went on the errand.
They were to go. The Spirit was to come. He would come before they went. They must not go until He had come. Then they were to go in His presence and power. They would be able to go because of Him. Their going would be worth while, because wherever they went He would be at work in them and through them. The real work would be done by Him. But it would be done through them. His presence was essential to their work being done. Their presence was essential to His doing His work. He would work as they went, and where they went.
That was the new blessed partnership of world-wide service planned by the Master as He went away. They would tell of Jesus. The Spirit would open doors, guide their tongues, guard their persons, and make the message of Jesus as a flame of fire in men's hearts.
Just before this, Jesus had talked a great deal with His disciples about the Holy Spirit. They didn't yet know how much this that He was saying, would come to mean to them. But they remembered after the Master was gone, and then they understood. When they got down into the thick of the world's crowds they understood the great significance of what He had said.
That last talk (John 14-16) they had together in the upper room and along the Jerusalem streets, on the betrayal night, was full of teaching about the Holy Spirit. And the next time after that that they met, in the upper room, (Joh_20:19-23) on the evening of the resurrection day, He breathed strongly upon them, and said, "Receive ye the Holy Spirit." And the very last word on the Olivet slope was, "Wait; wait until the Holy Spirit comes." He burned in deep that their dependence must be entirely upon the Spirit.
