Note, in John 5, where the Son of God is spoken of, we have, "He that heareth my word, and believeth on him that sent me, hath everlasting life." In chapter 6, where the Son of Man is spoken of, it is, "Every one that hath heard, and hath learned of the Father, cometh unto me"; "He that believeth on me hath everlasting life." Christ's voice as Son makes us know the Father for eternal life. The Father's teaching makes us believe on the Son of Man, come to Jesus, to have eternal life. It is clear the general truth of chapter 5 is the operation of Christ in power as Son of God, though the effect is to believe on the Father; whereas in chapter 6 Christ is the object as Son of Man. Yet, in all cases in John, Christ is looked at as down here, a Person known in the world in flesh. But in chapter 6 the Father draws to Christ in His humiliation.
