"We have the source." ~ Q (#1842)
Multiple meanings, I'm sure, but Christians often refer to Christ as "the Source," such as saying that Christ is the Source of All Life. (E.g., “Jesus Christ is the source." ~ James C. Dobson)
Jesus states, I am the bread of life (v. 35). Seven times in John the phrase I am is used with a predicate, including the passages on bread of life (6:35, 51); the light of the world (8:12; 9:5); the gate (10:7, 9); the Good Shepherd (10:11, 14); the resurrection and the life (11:25); the way, the truth and the life (14:6); and the true vine (15:1, 5). "The predicate is not an essential definition or description of Jesus in himself; it is more a description of what he is in relation to man" (Brown 1966:534). In these sayings Jesus' own identity and the salvation he offers are brought together (cf. Witherington 1995:158). It is in union with him that believers receive his salvation.
Jesus goes on to explain why they do not believe. The Father is the God who wills salvation, and Jesus is the agent of that will (vv. 37-40). Jesus begins with God's grace, that is, his act of giving: All that the Father gives me will come to me (v. 37). We just heard of the Father as the one giving them true bread from heaven (v. 32), and now the Father gives disciples to Jesus (cf. 17:2, 6, 9, 24). We are the Father's gift to his Son (cf. Loyd 1936:89)! Again the Father is seen to be the source of all. In one sense believers come to the Father through the Son (cf. 14:6), but in another sense they were already the Father's before they became disciples of Jesus. At this point we are at the edge of a great mystery, peering into the ineffable realms of eternity.
