7. Parting Discourses. In the Parting Discourses in Jn. Jesus speaks several times of going to the Father, 14:2, 3, 12, 28; 16:7, 28. In this respect it should not be overlooked that πορεύμαι alternates with ὑπάγω, which is used even more frequently by the Evangelist.8 In the main πορεύμαι occurs in sayings about the returning Lord and the Paraclete9 which form a more or less clear-cut complex of tradition within the corpus of the Parting Discourses.10 Fear of loneliness threatens the disciples as a result of the departure of Jesus (14: 1). Jesus meets this with the comforting assurance that He Himself will go on ahead to prepare a place (14:2) and that at His coming again He will take them up again into abiding fellowship with Himself (14:3). The departure of Jesus. however, is also of significance for those who remain in the world inasmuch as it will enable His disciples to do greater works on the basis of fellowship with the Father (14:12). Thus the going away of Jesus conquers both the uncertain [Vol. VI, p. 576] future (14:28a) and also the hostile and lonely present, since His going to the Father, who is the greater, implies exaltation for the Revealer (14:28). If in c. 14 the going to the Father is related to the coming again to the disciples, who are left in the world like orphans (14:18), in c. 16 the same going to the Father is the conditio sine qua non of the coming of the Paraclete (16:7 →  V, 813, 18 ff.),11 for only through His going can He be the Revealer who remains in the Spirit (16:7) and who thus overcomes all the sorrow of the disciples (17:6). Finally, the going to the Father is for the One who was sent from heaven and came forth from the Father the completion of His redemptive work on earth (16:28),12
