Death means death. The Bible has not redefined death as separation. If you show me the passage that says "death doesn't really mean death, but means separation", then I will concede. I don't care if you believe that God is going to torture people forever. I know what the Bible says.
The wages of sin is death, and Christ paid that price for us, so we may receive the gift of God, which is eternal life through Christ Jesus, our Lord.
Jesus was not annihilated; He was, however, forsaken by the Father. It is in this that we know what spiritual death is. Even more so when we look at the verses telling us that we were dead apart from Him, in our trespasses. And the verses telling us we have passed from death into life. Or that our bodies are dead because of sin.
So, clearly, you do not know what the Bible says.
And I never made the argument that God was going to torture anyone.
The wages of sin is death. Christ paid those wages on the cross with His death. If the penalty for sin is eternal torment in Hell as some people claim, then Christ didn't pay that debt, since He wasn't tormented in Hell forever. He died on the cross paying the debt of death that we owe. If Eternal Tormentism were true, then Christ's death on the cross wouldn't make sense. Since Annihilationism IS true, Christ's death on the cross makes perfect sense. He paid the price we owe.
The penalty was paid, eternal torment is not a punishment. Christ paid the debt and some refuse it; more shame to them. Christ also wasn't annihilated.
And if you want to argue His physical death was the punishment then you fail simply by the fact that those who are His still die physical death.
But if you want to go on contradicting yourself for all to see, so be it Johnny Knoxville.
