Jesus return is based on a wonderful future for us as humans ! this is an example of how in Governments like the US when picking a person for office. He does not take his seat right away once he has won the possition.
He has to be sworn in , then he takes his position at a set date.
Jesus has already been sworn in for his Government seat in Heaven, that is why it was written
. Luke 19: 11-12 So he said: “A man of noble birth traveled to a distant land to secure kingly power for himself and to return.
This is what the Sovereign Lord Jehovah says: ‘Remove the turban, and take off the crown. This will not remain the same. Raise up the low one, and bring low the high one.
A ruin, a ruin, a ruin I will make it. And it will not belong to anyone until the one who has the legal right comes, and I will give it to him.
That is why no more kings represented Jehovah in Isreal no temple exist there.
110 Jehovah declared to my Lord:“Sit at my right handUntil I place your enemies as a stool for your feet.”
1 Timothy 6:15
15 which the happy and only Potentate will show in its own appointed times. He is the King of those who rule as kings and Lord of those who rule as lords,
These will battle with the Lamb, but because he is Lord of lords and King of kings, the Lamb will conquer them. Also, those with him who are called and chosen and faithful will do so.”
This one will be great and will be called Son of the Most High, and Jehovah God will give him the throne of David his father,
And to him there were given rulership, honor, and a kingdom, that the peoples, nations, and language groups should all serve him. His rulership is an everlasting rulership that will not pass away, and his kingdom (Government) will not be destroyed.
This is what Jesus return means. But like on earth in these, office of Governments they put their own cabinet members in with them to rule
Jesus has his own cabinet number ,144, 000 will rule with him,
and you made them to be a kingdom and priests to our God, and they are to rule as kings over the earth.”
