Luke indicated that Jesus said that anyone who wanted to save his life (ὃς γὰρ ἐὰν θέλῃ τὴν ψυχὴν αὐτοῦ σῶσαι), would lose it or have it sent away (ἀπολέσει αὐτήν). Those who lost their life (ὃς δ’ ἂν ἀπολέσῃ τὴν ψυχὴν αὐτοῦ) for the sake of Jesus (ἕνεκεν ἐμοῦ), would save it (οὗτος σώσει αὐτήν). Jesus told his disciples how to save their lives. Something similar can be found in all 3 synoptic gospels. Matthew, chapter 16:25, Mark, chapter 8:35. and here, are almost word for word. Mark indicated that Jesus said that whoever wished, desired, or wanted to save his life, he would lose it. However, anyone who lost their life for the sake of Jesus, or for the sake of the gospel or the good news of Jesus, they would save their lives. This last phrase was not in the other 2 gospel stories. Matthew indicated that Jesus said that whoever wished, desired, or wanted to save their life, they would lose it. However, anyone who lost their life for the sake of Jesus, they would find their life. Is your life lost or saved?
There is no doubt that Jesus taught in Galilee, since this was his home base. Much like Matthew, chapter 4:12, and Mark, chapter 1:14, after his temptations, Luke had Jesus return to Galilee. However, Luke had no mention of the arrest of John, since he had already mentioned that earlier in chapter 3:19-20. John had Jesus also go back to Galilee in chapter 4:3. Luke said that Jesus was filled with the power of the Spirit (ἐν τῇ δυνάμει τοῦ Πνεύματος), a favorite and unique statement by Luke. He said that Jesus returned to Galilee (Καὶ ὑπέστρεψεν ὁ Ἰησοῦς…εἰς τὴν Γαλιλαίαν). Matthew had Jesus going to Galilee, just like his father Joseph had done years earlier. He used a citation from Isaiah to explain why Jesus was in Galilee. Galilee was about 80 miles north of Jerusalem and the Dead Sea area, originally part of the Israelite tribal territories of Issachar, Zebulun, Naphtali, and Asher, the northern tribes. Mark said that Jesus went into Galilee preaching the gospel or good news about God, while the message of Matthew was about the good news of the kingdom of heaven. Luke said that a report (καὶ φήμη) about Jesus (περὶ αὐτοῦ) spread throughout or over (ἐξῆλθεν) all the surrounding countryside (καθ’ ὅλης τῆς περιχώρου), but there was no indication in Luke what the message of Jesus was. Clearly, Jesus was active in Galilee.
This was another of Mark’s summary statements. Luke, chapter 4:44, has something similar, but Luke said that it was Judea and not Galilee. Besides, Luke did not mention anything about casting out demons. Matthew, chapter 4:23, is also somewhat similar. Matthew implied that Jesus went all over Galilee, as he was teaching in their synagogues. He said that Jesus was proclaiming the good news or the gospel about the kingdom, without saying whether it was the kingdom of God, the kingdom of heaven, or even an earthly kingdom. Here Mark said that Jesus went throughout the whole of Galilee (καὶ ἦλθεν…εἰς ὅλην τὴν Γαλιλαίαν), as he proclaimed or preached this unspecified message in their synagogues (κηρύσσων εἰς τὰς συναγωγὰς αὐτῶν). The synagogue was a new developing Jewish gathering place that might mean a group or assembly of Jewish people rather than a building, since some places may not have been able to afford a building. At the same time, Jesus was casting out demons (καὶ τὰ δαιμόνια ἐκβάλλων). Mark seemed very intent on emphasizing that Jesus was casting out demons along with his undefined preaching. He gave the impression that this took place all over Galilee without mentioning any particular place.
This summary statement seems to be unique to Matthew, but not inconsistent with the other gospel stories. This is basically the same as in chapter 4:23-24. However, there is no mention of Galilee here as in chapter 4. Instead Jesus was going through all the towns and villages (Καὶ περιῆγεν ὁ Ἰησοῦς τὰς πόλεις πάσας καὶ τὰς κώμας,) without restricting it only to Galilee. Otherwise, it is almost word for word like the earlier statement. Jesus was teaching in their synagogues (διδάσκων ἐν ταῖς συναγωγαῖς αὐτῶν). However, synagogue might mean a group or assembly of Jewish people rather than a building, since some places may not have been able to afford a building. Matthew said that Jesus was proclaiming the good news or the gospel about the kingdom (καὶ κηρύσσων τὸ εὐαγγέλιον τῆς βασιλείας), without saying whether it was the kingdom of God, the kingdom of heaven, or even an earthly kingdom. Jesus was like a faith healer, healing all diseases and curing people of all their sicknesses and illnesses (καὶ θεραπεύων πᾶσαν νόσον καὶ πᾶσαν μαλακίαν). In other words, he was this itinerant preacher healing people.
The question immediately rises is this about prophets in general, the prophet Isaiah, or the servant of Yahweh? Definitely the Spirit of Yahweh was upon this person. Not only that, but this disciple or prophet of Yahweh has been anointed, either like a priestly or a royal anointing. However, the primary mission is not cultic, but rather social in nature, what we might call social justice. Having been called by the Spirit and anointed by Yahweh, he was sent out. This would imply a time when there was no Temple, basically the exilic time. The generic mission was simple. Bring good news to the oppressed. The good news concept was later adapted by the early followers of Jesus who talked about the good news of the gospel. This basic mission included binding up the broken hearted and freeing prisoners that were clearly exilic problems and terms.
