Mark also the emphasis of _Jesus' own teachings_ regarding this second part of His mission. At the very beginning He spoke the decided words about the necessity of being born of the Spirit. And we are all impressed with that fact. But observe that several times, in the brief gospel record, He refers the disciples to the overshadowing importance of the _Spirit's control in the life_. And that He devotes a large part of that last long confidential talk which John records, to this special subject, pointing out the new experiences to come with the coming of the Spirit, and holding out to them as the greatest evidence of His own love _the promise of power_. It adds intense emphasis to all this to note that Jesus Himself, very Son of God, was in that wonderful human life of His utterly dependent upon the Holy Spirit. At the very outset, before venturing upon a single act or word of His appointed ministry, He waits at the Jordan waters, until the promised anointing of power came. What a picture does that prayerfully waiting Jesus present to powerless men to-day! From that moment every bit and part of His life was under the control of that Holy Spirit. Impelled into the wilderness for that fierce set-to with Satan, coming back to Galilee within the power of the Spirit, He himself clearly stated more than once, that it was through this anointing that He preached, and taught, and healed, and cast out demons. The writer to the Hebrews assures us that it was through the power of the Eternal Spirit that He was enabled to go through the awful experiences of Gethsemane and Calvary. And Luke adds that it was through the same empowering Spirit that He gave commandment to the apostles for the stupendous task of world-wide evangelization. And then at the very last referring them to that life of His, He said: "As the father hath sent Me even so send I you." Let me ask if He, very God of very God, yet in His earthly life intensely human, needed that anointing, do not we? If He waited for that experience before venturing upon any service, shall not you and I? But we must turn to the book of Acts to get fully within the grip of this truth. For it, with the epistles fitting into it, is peculiarly the _Holy Spirit book_, even as the Old Testament is the _Jehovah book_ and the gospels with Revelation the _Jesus book_. The climax of the gospels is in the Acts. What is promised in the gospels is _experienced_ in the Acts.
