I really do not want to go through all your comments....oh well..just those that I feel a need to improve upon...
John 1:4 refers to the word of God not Jesus....it had life in itself...it its message and expression of God was eternal life and we know it was possessed by his human Son.
The life of immortality the Father God gave his Son, indeed.
The power to lay his life down means that it was up to Jesus' human power and decision, along with his father's power as assist that possessed him, to stay the course, to the Cross. It is implying that Jesus at any time, could have decided even before his baptism to say no to all of it...he chose to die however.
And because Jesus had the power to go to the Cross, he automatically, had the power to raise it up, THROUGH his Father of course, as his Father commanded, and agreed...you die and I will raise you up to immortality , to new life as the first born of the new creation....
I've noticed you use the word inheritance of the Son from the Father. This does not work. God, who is the Son's Father does not give his divinity and his personality away to his Son as an inheritance somehow. The Father can only be himself, the one and only God. As if God would die and his Son would take over some how.....remember, the Son is still human not God. And God is not in the business of producing offspring of his complete self. That is found in the Greek mythology Section of the library.
