Can someone explain to me what Jesus meant with this?
Jesus was talking about the destruction of Jerusalem.
As they heard these things, he proceeded to tell a parable, because he was near to Jerusalem, and because they supposed that the kingdom of God was to appear immediately. (Luke 19:11 ESV)
The one who had one minas (or talent) was Jerusalem. It was taken and given to the Gentiles, who trampled the city underfoot, starting in 70 CE. Jerusalem did not want Jesus as their king. By 66 CE, the Gospel had beared great fruit in all places of the world EXCEPT for Jerusalem. They had chased out the disciples and killed those sent to preach repentance. If you read Revelation 4-6 in a historical context, and pair it with Matthew 24:14, it can be concluded that the end came in the first century and has been progressing according to God's plan (the sealed scroll of Revelation 5 and 6) since then.
I hope that helped any.
