Nah! I'll explain further. You can read it or not -- and no response is required.
Two "deaths" are described in the Bible.
Man's first death is appointed or required.
The second death is optional depending on whether one believes in Jesus.
Here is how that was set up.
Since sin and the second death passed to all mankind through one man, Adam; likewise, God will allow everlasting life to pass through one man to many others.
So the mission of the Word made flesh is to live a sinless human life.
To do that, He had to die sinless.
By doing so, He became the
only man to ever qualify as an heir to everlasting life under the original covenant.
At the end of time, His name is in the Book of Life.
However, He gifts His inheritance to all those who believe in Him as their Savior.
Thus salvation becomes a gift of God through Jesus Christ.
Only a man could accomplish this mission as the covenant was between man and God and only mankind dies.
Thus the Word had to be "made" flesh so that He became a party to the covenant as a man and so that He could die.
No spiritual being could do either of those two things!
=========================================================================
If Jesus returned to heaven as a man, then He did not die. Also, there's the minor fact that flesh & blood cannot inherit the Kingdom of God anyway.
If Jesus accepted His reward of everlasting by being born of the Spirit as a
new spiritual being as He entered heaven, then He cannot also
gift it to sinners who believe in Him.
=========================================================================
The Word lived on through Jesus' life and lives today and forever more.
The Word was "made" flesh as Jesus, and somehow this process was perhaps undone or reversed upon His ascension into Heaven. But man cannot understand the spiritual world in which this would have been accomplished.
On the other hand, what returned to Heaven of the man Jesus could simply be what returns for all of us -- our history, "spirits", or nature which is written in books to be used at the judgment.
Jesus' history contains no sins, and His name is written in the Book of Life as an heir to everlasting life. After all, that is all that's was required by His mission.
Believers become joint-heirs with Jesus:
The Spirit itself beareth witness with our spirit, that we are the children of God: And if children, then heirs; heirs of God, and joint-heirs with Christ ... (Romans 8:16-17)
Of course, Jesus gifted His reward to us.
That is what Christians believe:
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him, should not perish, but have everlasting life. (John 3:16)
God Bless You, OnewithHim!
