You are talking about the OT and the OT...teaches that hell, sheol is a pit or a grave...And yes the church did change the teaching to the age of accountability cause the idea of hell was too sickning and the church had to think of something after teaching the stuff of J. Edwards.
Reprobate infants are vipers of vengeance, which Jehovah will hold over hell, in the
tongs of his wrath, till they turn and spit venom in his face!"
"The view of the misery of the damned will double the ardour of the love and
gratitude of the saints of heaven."
The world will probably be converted into a great lake or liquid globe of fire,
in which the wicked shall be overwhelmed, which will always be in tempest,
in which they shall be tossed to and fro, having no rest day and night, vast
waves and billows of fire continually rolling over their heads, of which they
shall forever be full of a quick sense within and without; their heads, their eyes,
their tongues, their hands, their feet, their loins and their vitals, shall forever
be full of a flowing, melting fire, fierce enough to melt the very rocks and
elements; and also, they shall eternally be full of the most quick and lively
sense to feel the torments; not for one minute, not for one day, not for one
age, not for two ages, not for a hundred ages, nor for ten thousand millions
of ages, one after another, but forever and ever, without any end at all, and
never to be delivered."
Johathan Edwards...
