I don't believe we will be changed to have immortal bodies like He has until He returns at the last trumpet.
You are partially wrong. There's something missing in what you say above:
In the resurrection we will have the immortality
of Adam (the creature)
, which was
in Christ (our Creator)
, not the immortality of Christ (our Creator) Himself, who
alone has life in Himself. who alone is immortal:
"For as the Father has life in Himself, so He has given to the Son to have life within Himself" John 5:26
-- He alone possesses immortality and lives in unapproachable light, whom no human has ever seen or is able to see. To him be honor and eternal power! Amen. --- (1 Timothy 6:15-16, NETfree version).
"I am the First and the Last, and the Living One, and I became dead, and behold, I am alive for ever and ever, Amen. And I have the keys of hades and of death." Revelation 1:17-18.
Our life is in Christ, and in Him alone. The Spirit of God breathed life into Adam and he became a living soul. That's why we must be born of the Spirit in order to comprehend and experience the Kingdom of God. In the resurrection we will have the immortality of Adam, which was in Christ, not the immortality of Christ Himself, who alone has life in Himself. To believe that we are incapable of dying after we have regained the immortality of Adam through the resurrection, is based on not fully understanding the above, and this:
-----------------------------------------------------------------------------
".. you will most definitely die." (Genesis 2:17).
"You will NOT most definitely die. You will be like God" (who alone is immortal, who alone has life in Himself, and cannot die a second death). (Genesis 3:3-4).
--------------------------------------------------------------------------------
1. Death:
Mankind's first death is Adam's death. It came to all the children of Adam:
Through one man sin entered into the world, and death by sin, and so death passed on all men inasmuch as all sinned Romans 5:12
2. Resurrection:
Mankind both has already, and will yet experience one resurrection from death - Christ's resurrection, which takes place in Him just as much as death took place in Adam:
-- I am the Resurrection and the Life!
He who believes in Me,
though he die,
yet he shall live.
And whoever lives and believes in Me
shall never die -- John 11:25
3. 2nd death:
The lake of fire
IS the 2nd death:
And the sea
gave up the dead in it. And death and hades
delivered up the dead in them. And each one of them was judged according to their works. And death and hades were cast into the Lake of Fire. This is the
second death.
And if anyone was not found having been written in the Book of Life, he was cast into the Lake of Fire. (Revelation 20:13-15).
No one can die a 2nd death before he has been resurrected, because no one gets back Adam's immortality (which is in Christ) that Adam had before he lost it and became mortal, and eternal life is in Christ. Therefore the bodies of resurrected saints will be just as immortal as Adam's body was before he sinned and became mortal. Adam was immortal before he sinned and began to die, but His immortality was not the same as Christ's (who is God), rather, Adam's eternal life|immortality that he had before he sinned and began to die, was in Christ.
