In the parable of the Rich Man and Lazarus, Abraham and Lazarus are in Paradise, with water and light... on the other side of a chasm that's most difficult to cross, there looking at them is the Rich Man. He was in flames. In Jonah chapter two from the YLT we can read of Jonah, a precursor to Jesus, going down to the depths of the Earth, and he says prophetically, that those who lift themselves up to lying vanities show themselves no mercy. Abraham may have had idols as a boy, but after that, he was righteous and did not lift himself up to lying vanities. He accepted mercy. Jesus mentions that Israel in approximately 30 AD would only be given the sign of Jonah. Peter describes Jesus as preaching to those in gloomy dungeons, and the NT always relies on the OT for verification. Abraham and Lazarus as merely two examples, were not in gloomy dungeons. Believers in NDEs describe a feeling of unworthiness, followed by waves of God's love flooding over them. They are overwhelmed with mercy.
Scripture verses:
YLT
Jonah 2:8
8Those observing lying vanities their own mercy forsake.
NKJV
1 Peter 3:18-22.
18For Christ also suffered once for sins, the just for the unjust, that He might bring
[f]us to God, being put to death in the flesh but made alive by the Spirit,
19by whom also He went and preached to the spirits in prison,
20who formerly were disobedient,
[g]when once the Divine longsuffering waited in the days of Noah, while
the ark was being prepared, in which a few, that is, eight souls, were saved through water.
21There is also an antitype which now saves us—baptism (not the removal of the filth of the flesh, but the answer of a good conscience toward God), through the resurrection of Jesus Christ,
22who has gone into heaven and is at the right hand of God, angels and authorities and powers having been made subject to Him.
The Rich Man and Lazarus, Luke 16:19-31.
The Sign of Jonah. Matthew 12:38-42.
Noble Bereans. Acts 17:11.
He led captives and gifted them. Ephesians 4:7-10
I assert that while Jesus cleared out Hell in His resurrection, and this means much mercy and power for salvation now, over that of the OT times, I do not mean to say there is universal salvation, and it would seem some people today are trapped and locked in damnation. It is very unsafe to wait until after death to call on Jesus.
