I find John 3:13 covers those people who lived and died before Jesus' died.
When they are resurrected then they can learn about Jesus and decide to accept Jesus or not.
I find the definition of the lake of fire is: second death.
Even sinner Satan ends up in 'second death' as per Revelation 21:8.
Since Jesus will destroy Satan according to Hebrews 2:14 B, then ' second death ' is a fitting term for destruction.
Or as Psalms 92:7 says the wicked will be destroyed forever.
Jesus went to hell the day he died as per Acts of the Apostles 2:27.
Not to some religious-myth teaching about a fiery place, but to the biblical hell or sleeping place for the dead.
That is why Jesus taught sleep in death at John 11:11-14. (from Psalms 115:17; Psalms 146:4; Ecclesiastes 9:5)
In other words, Jesus was in sleep-like un-conscious state until his God resurrected Jesus out of biblical hell/grave.
You are right on it! But, now, you said for three days Jesus body was in Sheol / Hades, but what about the spirit form Jesus had been before coming to earth - it wasn't simply dead, nor on earth, nor in Hades. So, where was it? I'm almost positive you know. You've got everything else right so far.
