........ Basically for us, the messiah is simply the man who will rule from Jerusalem during the messianic era -- the last era of the earth before the resurrection... He will usher in this era of worldwide peace, and bring all the Jews out in the world back to the land of Israel. He is a very earthly leader. His kingdom is of THIS world.
" Thy kingdom come......" does connect to Earth.
What Isaiah 35th chapter describes is about: Earth.
When No one will say, " I am sick....." - Isaiah 33:24 - applies to Earth
And so does Isaiah 25:8 that death will stop on Earth.
Since 'Earth abides forever' - Ecclesiastes 1:4 B; Psalms 104:5 then what will be gone is: wickedness on Earth.
The wicked destroyed forever - Psalms 92:7; Psalms 104:35; Proverbs 2:21-22
So, to me it is the last era of bad earthly people and Not the planet before the resurrection.
A physical resurrection back to live life on Earth as the prophets in the old Hebrew Scriptures performed.
The difference for Christians is that Messiah will govern from a heavenly Jerusalem.
' Jerusalem above ' according to Galatians 4:26.
Then, we can meet people like King David who will be a prince on Earth - Psalms 45:16; Ezekiel 34:24; Isaiah 32:1
