Toward the end of the book of Matthew, Jesus mentions "all nations" or "all the nations" on four different occasions:
"Then they will deliver you up to tribulation and kill you, and you will be hated by
all nations for My name’s sake."
Matthew 24:9 (emphasis added)
"And this gospel of the kingdom will be preached in all the world as a witness to
all the nations, and then the end will come."
Matthew 24:14"
All the nations will be gathered before Him, and He will separate them one from another, as a shepherd divides his sheep from the goats."
Matthew 25:32"Go therefore and make disciples of
all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all things that I have commanded you; and lo, I am with you always, even to the end of the age. Amen."
Matthew 28:19-20
As we read these passages, it is important to keep in mind that the same person spoke them all (Jesus). The same person also wrote them all (Matthew). The same wording, "all nations," is used in them all (it's the same in the Greek as well as the English). Because of this, we can draw some conclusions:
First, followers of Jesus will face persecution and be hated by all nations.
Second, followers of Jesus are to proclaim the gospel to all nations.
Third, all the nations will face the final judgment.
Fourth, followers of Jesus are to make disciples of all nations.
It seems that Jesus, in giving us these statements, is also providing His followers with this overall conclusion: Despite the the persecution and hatred we will face from the nations, we are to nonetheless go to them proclaiming the gospel and making disciples, being motivated by the reality of the final judgment.
Like Jesus, we need to go to those who hate us and tell them the good news.
