To be honest with you, I’m significantly more concerned with my death, which will last forever.
Talk to Jesus about that.
That's His department.
John 5:24 Truly, truly, I say to you, whoever hears my word and believes him who sent me has eternal life. He does not come into judgment, but has passed from death to life.
He'll give you eternal life if you turn to Him, if you already haven't.
