We are purportedly born in Sin and require baptism for eternal life and the forgiveness of our Sins. If we do not get baptized we spend eternity in the Lake of fire.

It occurred to me, we only live as sinners for a short span
of time. There is a seeming inequity between living a few
years on earth and then spending Eternity in the lake of fire.

Not to question God, but why wouldnt he just make the lake of fire experience equal to the years we lived in the flesh?

Just saying the punishment doesnt seem to fit the crime!
