Sin can not take away your salvation.
Sin and death entered through Adam, Rom 5:12, 5:15-17 shows that, basically all died in Adam, in fact, the whole of creation died, Rom 8.
If sin could still kill spiritually again, then its fair to say, most would be dead again, they would be back in a pre-salvation state.
Then that would mean that Jesus would have to come back to earth again, and go to the cross again, to redeem mankind all over again, and then we would now have to have a third Adam!
We cant die again for sin, unrepentant, or unknown sin, or otherwise, because there is no more sacrifice for sin, it is done, it is eternal, unless we are to think that Jesus made a flawed new man, commonly known as the last Adam..last
.that word means it, last! It means no more Adams.
Heb 10:18 Where there is forgiveness of these, there is no longer any offering for sin.
Lets not give Adam #1 more credit than Adam#2, our Lord.
Since the first adam killed us all eternally, then I know that the last made us alive eternally.
Leaving even the doctrine aside for a moment, your logic here is basically a bunch of non-sequiters.
Sin entered through Adam and sin brought death. (
yes, we agree)
All died in Adam (
Yes, we agree)
if sin could kill again then most would be dead again and back in a pre-salvation state.
(
We have a slight disagreement here because of my views on sacramental grace etc. But for the sake of discussion I'll ignore them for now. In my view the state of a Christian fallen into mortal sin is different than a person who was never a believer, but set that aside for the moment).
Then that would mean that Jesus would have to come back to earth again, and go to the cross again, to redeem mankind all over again, and then we would now have to have a third Adam!
Here is where the logical wheels fall off. None of this conclusion actually follows from the previous statements.
I'm going to assume that you would agree that Jesus secured an unlimited supply of grace and forgiveness by his once for all sacrifice.
At this point there are two logical possibilities.
#1 - Receiving that grace and forgiveness is conditional upon something you do, such as repentance and giving your allegiance to God etc.
#2 - Receiving that grace and forgiveness is conditional only upon God deciding to give it to you, completely regardless of anything you do or don't do.
If you select option #2 above then there are two further possibilities
#1 - God decided to give this grace and forgiveness to everyone, therefor everyone is saved, regardless of what they do. In this case our conversation here has no meaning and is a complete waste of time. Indeed Christianity itself is pointless and really a waste of time.
#2 - God decided to give this grace and forgiveness only to certain people, therefor those certain people are saved regardless of what they do. Everyone else is going to hell, regardless of what they do.
If you select option 1 above, then everyone is saved no matter what and there is no point to any of this conversation or Christianity itself for that matter.
If you select option 2 above then there are 2 further options
#1 - The grace God gives automatically transforms people so that they stop being wicked.
#2 - The grace that God gives does not automatically transform people, thus they continue to be wicked.
In case #1 above, the response to grace is mechanical and this whole conversation would be pointless because you have no real say in whether you sin or not. In this case, the only point of Christianity is essentially to point out those people who are saved by demonstrating that they are being transformed. This would also suggest that your arguments is incorrect since the saved people should stop sinning because grace is transforming them.
In case #2 above, there is no real response to grace and again this whole conversation is pointless, and indeed all of Christianity is pointless and makes no difference whatsoever.
Now, if you go back to the original choice and select option #1, this is the only case in which our conversation actually matters or has any real meaning. Thus if you pick any of the other options you should probably just stop wasting everyone's time by posting pointless meaningless conversations.
If we receive grace from Jesus based upon our asking for it, or accepting it, or repenting, or whatever other condition you prefer, and his supply is limitless, then all you would have to do is repeat the condition under which you received the grace to begin with.
Your argument is imposing an assumed limitation on Jesus' supply of grace and forgiveness to one per person. So once you received yours, he'd have to go get more if you messed up your first round.
Your assumption is apparently that because the sacrifice by which Jesus obtained grace and forgiveness for us was a one shot deal, that therefor its availability to us must also be a one shot deal.
However, it's not the one shot sacrifice which has to be repeated in order for us to receive more grace and forgiveness. Its the condition under which we receive them that has to be repeated. In other words, you have to ask again, or accept again, or repent again (or whatever condition you prefer).
