Getting back to the OP
This very short summary of Who Holds Immortality still applies:
As David wrote, “He (Jesus) asked life of You (God), and You (God) gave it to him, length of days forever and ever” (Psalm 21:4).
Jesus affirmed, “The Father has granted the Son to have life in Himself” (John 5:26).
Jesus declared, “I am the bread of life” (John 6:35) and, “I am the way, the truth, and the life. No one comes to the Father (for Life) except through me” (John 14:6).
Read it carefully and you will see why and how Jesus is the first fruits of them that sleep. You will also see how high God exalted His Son in raising him from the dead and blessing him with Life Eternal. The first of his brothers!
For he who sanctifies and those who are sanctified all have one source. That is why he (Jesus) is not ashamed to call them brothers, saying, “I will tell of your name (God's Name) to my brothers; in the midst of the congregation I will sing your praise.” Hebrews 2:11-12
For those following this discussion, it's worth noting that Zao has consistently avoided addressing these specific passages and seems to deny a fundamental truth, one that David, Jesus, and Paul each affirmed with unmistakable clarity. There is no ambiguity in these verses; they all point to the same, consistent truth.
