According to Josephus, Jesus had Jewish and non-Jewish followers, so apparently He wasn't limiting his message.
sidenote: Although Josephus mixed in his own speculations into his writings, his historical notations should hold at least some credence.
Jesus was evasive, selective and at times in coherent.
Matthew 19:5 These twelve Jesus sent out with the following instructions: "Do not go among the Gentiles or enter any town of the Samaritans.
I list the verse first followed by the point I am making to show Jesus was not well understood.
Mark 4:34 In fact, in his public ministry he never taught without using parables; but afterward, when he was alone with his disciples, he explained everything to them.
1. So unless you were his disciple. Jesus's teachings remain unexplained to the public.
Luke 18:31 Jesus took the Twelve aside and told them, "We are going up to Jerusalem, and everything that is written by the prophets about the Son of Man will be fulfilled.
32 He will be handed over to the Gentiles. They will mock him, insult him, spit on him, flog him and kill him.
33 On the third day he will rise again."
34 The disciples did not understand any of this. Its meaning was hidden from them, and they did not know what he was talking about.
2. Even the disciples did not understand and did not know what Jesus was talking about even after the resurrection. So Jesus never got over his bad habit of speaking in parables and remained inarticulate, incoherent.
Luke 8:10 He said, "The knowledge of the secrets of the kingdom of God has been given to you, but to others I speak in parables, so that, "'though seeing, they may not see; though hearing, they may not understand.
3. Now it is not Jesus's explanation that can reveal to the disciples, but God has to give them that knowledge. Because Jesus only speaks in parables.
John 16: 25 "Though I have been speaking figuratively, a time is coming when I will no longer use this kind of language but will tell you plainly about my Father.
4. A time will come when Jesus will speak plainly, coherently. But unfortunately Jesus was put to death before he could. The time for Jesus speaking plainly has passed. Check point 2.
1 Corinthians 2:10 these are the things God has revealed to us by his Spirit. The Spirit searches all things, even the deep things of God.
5. Maybe it is the Spirit that can reveal all things. But we know the Spirit was not getting through to tbe disciples. They constantly complained they did not get what Jesus was saying. Are we in a conundrum??
