How do I desire eternal life, knowing I'll always be the man who committed my sins?

The new creation idea doesn't help me much. I'm just an improved version of myself in the resurrection.

I'll always be the man who did some terrible stuff. My sins are forgiven, but I'll always be just a "sinner saved by grace" in my identity.

And I know God is right, but I just can't see how.

So, how does the Christian faith resolve this? How do I desire eternal life, if I'll always be the man who did terrible things?

Searching for meaning on this.
