Is Jesus’ message for the Whole World?

It was necessary for Jesus to minister personally among the Jews with signs and wonders in order to confirm to them that he was the long-awaited Messiah, the Blessed One, the Anointed One whom God had sent to redeem His chosen people. For this reason during his personal ministry, Jesus instructed his disciples to go only to the Children of Israel:

And you are heirs of the prophets and of the covenant God made with your fathers. He said to Abraham, “Through your offspring (descendants), all people on earth will be blessed.” When God raised his servant (Jesus the Messiah), He sent him first to you to bless you by turning each of you from your wicked ways.
Acts 3:25-26

It is important to realize that the second part of Jesus’ mission was most significant. That mission was to give his life a ransom for the sins of all mankind (1 Timothy 2:4-6). This was the blessing that was for all nations — the good news that Jesus, by the shed blood of his suffering on the cross, paid the penalty for the sins of mankind, and that whoever accepts this blessing of salvation is assured eternal life with God. Thus It is not that Jesus was sent only to the Jews rather that men are able to preach his full message only after he has fulfilled the Jewish prophecies through his death and Resurrection. It is the witness to this that is then preached by his disciples in all nations of the world. This is what is written:

“The Christ will suffer and rise from the dead on the third day, and repentance and forgiveness of sins will be preached in his name to all nations, beginning at Jerusalem.” (Luke 24:46-47)

The Scriptures are clear that this salvation in Jesus the Messiah is available for all people, both Jews and Gentiles of all nations:

“and this good news of the kingdom will be proclaimed throughout the world, as a testimony to all the nations, then the end will come” (Mt.23:14)

“and that repentance and forgiveness of sins should be proclaimed in his name to all nations, beginning from Jerusalem” (Luke 24:47)

“You will be my witnesses in Jerusalem, and in all Judea, and Samaria, and to the ends of the earth.” Acts 1:8

… go and make disciples of all nations (all people)” (Matthew 28:19 (also Mark 16:15))

Jesus himself confirmed the universal nature of his mission:

I am the Light of the world. Whoever follows me will never walk in darkness, but will have the light of life.” (John 8:12)

Even the Qur’an seems to points to a universal mission of Jesus:

… and (We wish) to appoint him (Jesus) as a Sign unto men (“ayatan lilnnasi – النَّاسِ, this can be “people” but also frequently “mankind” in the Qur’an      ), and a mercy from Us. Surat-u Maryam (Q 19:21)

Jesus came to save everybody (1 John 2:2). Jesus Christ is God Himself (John 1:1). Jesus died on the cross as the payment for all our sins, and He rose from death in resurrection (1 Corinthians 15:3–4). Jesus said He was the Good Shepherd, and He predicted that His flock would be greatly expanded: “I have other sheep that are not of this sheep pen. I must bring them also. They too will listen to my voice, and there shall be one flock and one shepherd” (John 10:16).

In all three Synoptic gospels relate at least the one same occasion on which Jesus goes into the Gentile region (Luke 6:17-19, Matt.15:21, Mk.7:24). In the Lucan portrayal, people from Tyre and Sidon come to Jesus for healing and exorcisms; these are places well beyond the Jewish regions (Jerome p.1313)

In Summary, Jesus ministered principally to his people Israel, because the prophecies were made in an Israeli context, and so also the fulfilment was in the same context. As per the Scriptures ,all nations would then be called “to worship at Mount Zion”.

“And it shall come to pass in the last days, that the mountain of the Lord’s house shall be established in the top of the mountains, and shall be exalted above the hills; and all nations shall flow unto it.” – Isaiah 2:2 

In all the Synoptic Gospels Jesus is quite clear that his Good News is for all the world:

“And the good news must first be proclaimed to all nations…” (Mark 13:10, Matt.24:24)

It is clear that no prophet is to come after him, Jesus makes it very clear that anyone claiming to come after him who is not him is false. All that is left is his return on Judgement Day. This is again corroboration that if Jesus is not for the whole world, then no one else is. The same passage from above continues:

“…And if anyone says to you at that time, ‘Look! Here is the Messiah!’ or ‘Look! There he is!’—do not believe it. False messiahs and false prophets will appear and produce signs and omens, to lead astray, if possible, the elect. But be alert; I have already told you everything. “But in those days, after that suffering, the sun will be darkened, and the moon will not give its light, and the stars will be falling from heaven, and the powers in the heavens will be shaken. Then they will see ‘the Son of Man coming in clouds’ with great power and glory. Then he will send out the angels, and gather his elect from the four winds, from the ends of the earth to the ends of heaven.” (Mark 13:24-27, also Matt. 24, Lk.21)
