For example: Christ had eternal life when he was here (John 5:26, 1John 1:1-2)
but according to Rom 6:9 and Rev 1:18, he didn't obtain immortality till he rose
from the dead.
Likewise Christ's believing followers have eternal life while they're here (John 5:24)
but according to Rom 8:23-25, 1Cor 15:51-53, and 1Thss 4:14-17 they won't
obtain immortality until their resurrections.
So then; I think we can safely conclude (in a nutshell) that immortality is
something that can be seen, while eternal life is something that cannot be seen.
The properties of eternal life are a little easier to understand when juxtaposed with
creature life.
Human life was created.
Eternal life wasn't created.
There's a large variety of created life.
There is only one eternal life.
Human life's primary characteristic is human nature; roughly defined as the
fundamental dispositions and traits of the human being.
Eternal life's primary characteristic is divine nature, roughly defined as the
fundamental dispositions and traits of the supreme being.
FYI: When people in possession of eternal life pass away, they are fully prepared to
go straight to heaven because God has devised a way to strip them of their human
nature and leave them with only the fundamental dispositions and traits of the
supreme being (Col 2:11). That's quite an advantage, and emphasizes the
importance of obtaining eternal life now, today, while it's available.

I agree with most of what you posted, except the part about God and Christ.
The word immortal also means uncorruptable, or
incorruptable. Of course man being mortal is also
corrupted by sin, and his mortal body does see corruption because of sin.
But God and Christ are not
corrupted by sin, therefore neither did Christs body
see corruption as is also written.
Psalm 16:10
For thou wilt not leave my soul in hell; neither wilt thou suffer thine Holy One
to see corruption.
Acts 2:27
Because thou wilt not leave my soul in hell, neither wilt thou suffer thine Holy One
to 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.
Acts 13:35
Wherefore he saith also in another psalm, Thou shalt not suffer thine Holy One
to see corruption.
Acts 13:37
But he, whom God raised again,
saw no corruption.
Christ is the
incorruptable seed, therefore He is the immortal and Eternal life.
1 Peter 1:23
Being born again, not of corruptible seed,
but of incorruptible, by the word of God, which liveth and abideth for ever.
1 Timothy 1:17
Now unto the King eternal,
immortal, invisible, the only wise God, be honour and glory for ever and ever. Amen.
1 Timothy 6:16
Who only hath immortality, dwelling in the light which no man can approach unto; whom no man hath seen, nor can see: to whom be honour and power everlasting. Amen.
