I'm totally lost on the firstborn thing It sounds like you're saying that when the Bible refers to Jesus as the firstborn, that is referring specifically to him being the first raised from the dead--but that doesn't make any sense because others were resurrected in the old testament. Unless he was the first resurrected to heaven. Can you clarify this, please?
Bluecanary,
I pondered this same problem over 30 years ago and came to understand what happened at the resurrection after carefully listening to the texts on tape. Resurrection under New Testament rules is not the same as it was with the resurrection of the others you mentioned. Why? Because anyone resurrected under New Testament rules while still human, would be immortal. Paul make this clear enough when He corrected Corinthian thinking and this would be true for anyone raised for any reason. The seed we sow is human and will be raised human. Now was Jesus not raised a little early as an immortal human for such rules to take effect? No for Jesus gave up his non-human seed or life to begin with and could get it back. Furthermore He gained immortality as a human before He died so it did not matter for Him. His resurrection was the first of such future immortal human resurrections promised for the rest of us. This is also the very reason why all humanity raised by Him would now qualify to be immortal. He regained what Adam lost when he was prevented from eating of the tree of life. The thinking goes according to its Kind, like for like, the purpose of the tree of life in the first place with its intended use and such teachings of the past that apply to us as humans. How this immortality happened and when is another discussion but I put it at His transfiguration. That is the only event during His ministry that seems to fit.
But I must add that there is another detail that made all this confusing to me. What? The resurrection of Jesus as the non-human He was before He became flesh and known as the Word or Logos. Or put another way, the resurrection the life and Nature of the one now known as Jesus as the God and creator of us that was appointed over us by God Himself in the beginning of the human race as John testified in John 1:1. Nothing unusual about using the expression God in this way by Jews as the scriptures did it in several places and it does not make two true God’s or Supreme Beings but everyone seems to have a fit over it. It was not everyday or frequent use and many did not grasp it even back then. So what did happen in the special case of Jesus? Well God answered His prayer when Jesus prayed: John 17:1 These words spake Jesus, and lifted up his eyes to heaven, and said, Father, the hour is come; glorify thy Son, that thy Son also may glorify thee: 2 As thou hast given him power over all flesh, that he should give eternal life to as many as thou hast given him. 3 And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent. 4 I have glorified thee on the earth: I have finished the work which thou gavest me to do. 5 And now, O Father, glorify thou me with thine own self with the glory which I had with thee before the world was. 6 I have manifested thy name unto the men which thou gavest me out of the world: thine they were, and thou gavest them me; and they have kept thy word. 7 Now they have known that all things whatsoever thou hast given me are of thee. 8 For I have given unto them the words which thou gavest me; and they have received them, and have known surely that I came out from thee, and they have believed that thou didst send me. This is what happened then at that time. As the Logos or Word was now made alive once again, and as the creator of the human race given him, it was no problem for this Word to raise the body that was executed and take on both Natures seamlessly in order to fulfill the tasks still assigned to Him. We still refer to Jesus as fully human and He will return as a human to raise the dead and rule as testified to in Acts 1, but we also see the Nature of the non-human that appeared to Paul and chose Paul to be his Apostle to the Jews and Gentiles so as not to confuse this event with His coming again as a man. I decided to call this the hypostasis nature of Christ as the generic meaning of this Trinitarian term fits. And since we had no such prior seed or life this dual nature does not apply to us. Further details of how this could be are simply not make known to us other but the reality of it was explained in scripture as brought out in this thread.
