They knew that His personal presence was no longer to be with them, and they recognized, as they had never recognized before, the value of the opportunities that had been theirs to walk and talk with the Sent of God. Many of His lessons, when spoken, they had not appreciated or understood; now they longed to recall these lessons, to hear again His words. With what joy now came back to them His assurance:— “It is expedient for you that I go away; for if I go not away, the Comforter will not come unto you; but if I depart, I will send Him.” “All things that I have heard of My Father I have made known unto you.” And “the Comforter ... whom the Father will send in My name, He shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you.”[113] [Sidenote: _The Teacher of Truth_] “All things that the Father hath are Mine.” “When He, the Spirit of truth, is come, He will guide you into all truth.... He shall receive of Mine, and shall show it unto you.”[114] The disciples had seen Christ ascend from among them on the Mount of Olives. And as the heavens received Him, there had come back to them His parting promise, “Lo, I am with you alway, even unto the end of the world.”[115] [Sidenote: _Faith’s Assurance_] They knew that His sympathies were with them still. They knew that they had a representative, an advocate, at the throne of God. In the name of Jesus they presented their petitions, repeating His promise, “Whatsoever ye shall ask the Father in My name, He will give it you.”[116] Higher and higher they extended the hand of faith, with the mighty argument, “It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us.”[117] Faithful to His promise, the Divine One, exalted in the heavenly courts, imparted of His fulness to His followers on earth. His enthronement at God’s right hand was signalized by the outpouring of the Spirit upon His disciples. [Sidenote: _The Final Preparation_] By the work of Christ these disciples had been led to feel their need of the Spirit; under the Spirit’s teaching they received their final preparation, and went forth to their life-work. No longer were they ignorant and uncultured. No longer were they a collection of independent units or of discordant and conflicting elements. No longer were their hopes set on worldly greatness. They were of “one accord,” of “one mind and one soul.” Christ filled their thoughts. The advancement of His kingdom was their aim. In mind and character they had become like their Master; and men “took knowledge of them, that they had been with Jesus.”[118] [Sidenote: _A Work That Shook the World_]
