Ok, you make a good argument.
But surely the greatest demonstration of love you can show Jesus is not accepting his sacrifice.
You show you are willing to suffer forever, separated from God, because you cannot accept another to suffer on your behalf. Because it is not fair, not just and you love Jesus.
Therefore if God is really a good, righteous, just, fair and loving God - He will see your act as the ultimate sacrifice, forgive you and welcome you into His house. You are willing to suffer eternally out of pure love for your God and His Son! What greater show of love and faith can there be?
Me: But why would you do this for me?
Jesus: Because I love you.
Me: But it doesn't seem fair.
Jesus: That's right. It's not fair at all -- it's merciful. It is, after all, a gift.
Me: But how can I possibly deserve such a gift?
Jesus: Don't be silly. You can't. You don't. This gift is offered because I love you and want to help you, not because I owe it to you.
Me: No Jesus, i won't accept your blood on my hands.
Jesus: But if you do not you will be suffer for eternity.
Me: Better that than see you suffer on my behalf, you are innocent, i am not - this is the right thing to do.
Jesus: You love me so much that you willingly damn yourself?!
Me: Yes Master, i'd rather be damned than benefit from your pain.
Jesus: Such a sacrifice would be greater than mine! Truly you are worthy of eternal life.
