Of all the oil diggers in history who have ever struck coveted crude, none of them saw in those moments what Jesus saw in this one. Jesus could see that his life and ministry would ultimately tap a cascading flow of life in his followers and that it would cover the planet.
No religious leaders asked Jesus to take part in the "Great Outpouring" ceremony that day. He had not been commissioned by any man to do so. His name was not on the order of worship written out by the scribes and Pharisees. Nor did he ask anyone for permission. He simply and powerfully lifted his voice uninvited and unannounced. He was on heaven's agenda that day. The announcement was his to make. It erupted; it poured forth. There was no more appropriate or meaningful moment for Jesus to prophesy the powerful coming work of the Holy Spirit, of the Day of Pentecost and the events of the Book of Acts, than then and there. Just as John the Baptist had heralded the coming of the Messiah in the wilderness bold and unhindered, so now Jesus was heralding the coming of the Spirit in a most liberated and authoritative manner.
Christ had come to them; the Spirit would soon pour from them.
