A great question!
Since everyone ends up dying, then it makes sense to ponder the question, don’t you think?
Benjamin Franklin apparently said: “… in this world nothing can be said to be certain, except death and taxes.”
Not everyone pays tax, but everyone gets to die!
So what happens next?
Nothing? Recycling? Come back as a unicorn? Heaven? Hell?
What have you decided? Is it a fixed thought, or waiting for more enlightenment?
I hope to end up in heaven. Not because I am any better than anyone else, but because I am forgiven by God. That happened when I accepted what Jesus did for me on the cross. He then came to life again, so I will be able to also.
