Pronger1. Rev 5 has nothing to do with the 144,000
"The 144,000 is the great multitude fulfilled in an unexpected way for the Jews"
No. No. No.
Ex 19:5,6 "Now if you will strictly obey my voice and keep my covenant, you will certainly become my special property out of all peoples, for the whole earth belongs to me. You will become to me a kingdom of priests and a holy nation.’"
That is fulfilled in 1 Pet 2:9 "But you are “a chosen people, a
royal priesthood, a holy nation, a people for special possession, that
you should declare abroad the excellencies” of the One who called you
out of darkness into his wonderful light."
That was supposed to go to Israel but they were unfaithful and it was transferred to spiritual Israel.
When Jesus was on earth, neither he, nor Peter nor Paul, knew how many would make up spiritual Israel. Jesus said little flock. But he later learned when he got the Revelation that it would be 144,000.
Revelation 5:9,10 & 20:4-6 says that those who are raised to heaven in the first resurrection are to be kings and priests with Jesus. The number 144,000 makes sense to assist Jesus. They are anointed with holy spirit as anointing is what makes a king.
Jesus was resurrected in a spirit body.
John 2:21 "But he was speaking of the temple of his body" was John's commentary about what Jesus said. We can not take that as fact.
What Jesus said to Thomas does not change things. He was not a ghost or spirit at that time because he had taken on a body.
