He Named the Father as Sender in John Only
In the Synoptics Jesus says he was 'sent' but never names who sent him — that disclosure belongs exclusively to John.
Across the four gospels, Jesus uses the language of being 'sent' to describe his mission. In Matthew, Mark, and Luke, he uses this language sparingly and without naming a sender in the first person. In Matthew 15:24 he says 'I am not sent but unto the lost sheep of the house of Israel' — sent, but by whom is left unstated. In Luke 4:43 he says 'I must preach the kingdom of God to other cities also: for therefore am I sent' — again, no sender named. In the Gospel of John, however, the sender is named explicitly and repeatedly in Jesus's own speech. 'The Father which hath sent me' appears as a phrase Jesus uses again and again: John 5:36, 5:37, 6:44, 8:16, 8:18, 12:49, 14:24, and more. The pattern is consistent enough to constitute a structural difference between the Synoptic and Johannine presentations of Jesus's own self-description. In John, the sender is not merely implied — Jesus names him: 'the Father that sent me.' This naming of the Father as the specific agent of the sending is, in the red-letter corpus, a feature that belongs almost entirely to John. The Synoptics leave the sender grammatically absent; John fills that gap in Jesus's own voice, repeatedly and deliberately.

He that loveth me not keepeth not my sayings: and the word which ye hear is not mine, but the Father's which sent me.
Evidence Notes
Matthew 15:24 and Luke 4:43 use passive 'sent' with no named sender in Jesus's speech. John 5:36, 5:37, 6:44, 8:16, 8:18, 12:49, 14:24 all contain Jesus explicitly naming 'the Father' as the one who sent him. A full scan of Synoptic red-letter text finds no instance where Jesus names 'the Father' or 'God' as the agent of his sending in first-person speech.
Greek Note
The Greek verb apostellō (to send, commission) and its cognate pempō appear throughout the Johannine red-letter passages with 'the Father' (ho patēr) as the explicit grammatical subject. In the Synoptic instances the passive construction (apestalpmai in Luke 4:43) leaves the subject unspoken.
