What you hear through me, are the teachings (power) of God's Holy Spirit, with scriptures, and not that of the wisdom of men, aka the many doctrines of denominational Churh-ianity (worldly logic).
1 Cor. 2[5] That your faith should not stand in the wisdom of men, but in the power of God.
So then, what you command me to do, according to scripture, has been done!
My mind HAS BEEN renewed through the teachings by the Holy Spirit of God, and not that of the wisdom of men.
Then you should drop the term immortal body. That is mythology. Paul said there was a corruptible body and an incorruptible body. That is the Scriptural terms to use. There is a temporal dead physical body, and a permanent live physical body. 2 Corinthians 5:1.
A body will always be physical. That was true from Genesis 1.
The term mortal means death. The term immortal means not death. Both words still have death in their connotation. Perhaps it is OK to say that Adam's body is death, and God's given body is life? "Non death" (immortal) still gives a carnal sentiment. Just saying. You don't like church-ianity. But replacing your lingo with Latinized Greek mythology, and what Hollywood portrays, seems the wrong direction.
I get it that Paul used a Greek term, but he was explaining death puts on life, and the English translators went with the Latin equivalent instead of just using death puts on life, which is the English equivalent.
Now people are just confused and go with the carnal thinking of immortal. The word is not dealing with the body, but with the spirit. You are dead without your spirit. When you put on your spirit you are leaving death for life. That is being glorified and a restored son of God, not just in name, but reality.
And Jesus always had a spirit and an incorruptible physical body. Jesus was never in Adam's dead corruptible flesh, without his spirit. Jesus was human with a physical body, but without sin, which means without a body of corruption. Not that He was just obedient. He was the Lamb without blemish in all ways. Having Adam's dead corruptible flesh would mean He was blemished. He was not just a perfect example, He was God, and without death from the womb of Mary, not that He needed to die and be redeemed like us. He was our redemption, so without blemish from conception to eternity. Jesus was always the spotless Lamb slain, even before creation.
Immortal means not dead, it does not mean not corrupt. Jesus' body was only dead for 3 evenings and mornings. It was not dead between conception and the Cross, nor in a state of death as we all are even though physically alive. Nor did that body ever see corruption. Acts 2:31
"He seeing this before spake of the resurrection of Christ, that his soul was not left in hell, neither his flesh did see corruption."
BTW, your "single factor" lands in "other" of my multiple choice.
Other is the only Scripturally option. None of the other options even hint at Scripture.
Mortal = death.
Spirit = light
Spirit and mortal = light and death
Immortal = not death
Immortal and Spirit = not death and light
Jesus only displayed His Spirit one time on the mount of Transfiguration to Peter, James, and John.
Jesus always had His Spirit, but never publicly displayed this part of His being.
"And was transfigured before them: and his face did shine as the sun, and his raiment was white as the light."
Spirit is light, and put on by every one in Christ at one point in time. The 5th Seal. That is why Paul calls it death putting on life. A few more verses:
"And they that be wise shall shine as the brightness of the firmament; and they that turn many to righteousness as the stars for ever and ever."
"Then shall the righteous shine forth as the sun in the kingdom of their Father."
We are to shine spiritually as a light in the world. But eternal life is still a physical light having on the spirit. Creation is both spiritual and physical, not in contrast to each other as some posit it philosophically.
There is plenty of Scripture showing God is light and not just in a symbolic form. Actual light that replaces the need for created lights. Starting in Genesis 1, when creation was darkness, and God declared there to be light.
