What happens is, when I perform, I'm somewhere else. I go back in time and get in touch with who I really am. I forget my troubles, my worries.
If you aren't in the moment, you are either looking forward to uncertainty, or back to pain and regret.
As a Christian, Christ died so that we will have eternal life in Him in Heaven. What it looks like doesn't matter, what it smells like doesn't matter, as long as Christ is there it will be Heaven to me.
