Perhaps I should state my position here that I don't think the physical should overshadow the spiritual. I do believe that the death Christ died was a spiritual death as the sin of the world, and of the ages for that matter, where placed on Him.
But neither do I believe we should ignore the physical either. If it didn't matter, Christ died (the physical death) for no reason, and a baptism would have sufficed. There are two aspects to this that I don't think should be isolated from one another. After all, scripture speaks of two deaths and two resurrections.
For instance, John 11:26 was quoted, saying "
And whoever lives and believes in Me shall never die. Do you believe this?". Through belief in Christ and His work we have gone from being spiritually dead (no exceptions) to spiritually alive, never to experience this death again.
However, we also have John 11:25 which says, "Jesus said to her, “I am the resurrection and the life. He who believes in Me, though he may die, he shall live". This is speaking of a physical death and I know this because of the conditional wording "even if ever he may die"
combined with the clause of believing in Him. If one is believing in Him, he is not spiritually dead any longer and therefore will not die in this sense. Yet He says that if that person dies or has died (aorist tense), will live (future tense). [Please don't make too much of me pointing out the tenses]
This is some of why I believe death and life are not merely spiritual or physical but both. If in Christ, we have been risen spiritually never to die again, and yet if we die (in the physical) we will live (in the spiritual).
For further clarification, I do not believe in a resurrection of my physical body, for it is but a naked kernel not resembling the body to come (not that I know what that is). The point is that physical death will not impair my life, but rather increase it.
And now I'll get to my real point; I don't think Christ's sacrifice was "substitutionary" in the sense of "in my place". It was "for" me, not "instead of me". I can't find any place in scripture which suggests He went in my place to do something I could have done. (Please post if you know of any.) I could not make the sacrifice He made, not even for myself let alone for anyone else. What I
could do however is die, period, in all senses of the word.
Basically, the wages of sin IS death, not was death, or would have been death. Neither do I think it means any particular slant on death; just death, utterly and completely in any manner you can conceive. I believe that the sentence has to be carried out fully and completely as well, otherwise God's Holy character is compromised. Can God simply say "don't worry about that sin, I forgive you and it's all alright" just because we say we are sorry and DO something (even if that doing is just believing in Him)?
Or is there even more happening here? I think there is.
