In relation to your many verses which clearly teach that the soul (life of a person) is saved from the grave:Jonah 2: 1-7 describes Jonah crying out from the "depth of Sheol". The belly of the whale was not a grave. No, Jonah died and cried out to God. "Water encompassed me to the point of death ... I descended to the roots of the mountains, the earth with its bars (gates) was around me forever, but You have brought up my life FROM THE PIT, O LORD my God."
Luke 16:23-31 is not a parable! Parables don't mension names of real people, like Abraham. What moral truth could be gained from describing a place that does not exist? Parables don't describe fictional, abstract territories.
Save from the Grave Shall he deliver his soul from the hand of the grave? Psa. 89:48.
But God will redeem my soul from the power of the grave. Psa. 49:15.
His soul from the pit. Job 33:18; Psa. 30:3.
Thou hast delivered my soul from the lowest hell (or grave: see Marg.). Psa. 86:13.
Thou hast in love to my soul delivered it from the pit of corruption. Isa. 38:17.
The Bible is consistent in its message that the whole person enters the grave (sheol, hell, hades, Gehenna etc)
Unfortunately, you’ve adopted a set of introduced notions and are holding onto them so tightly that they are leading you away from a sound reading of the text.
You even quoted the signs of Jonah and yet you still miss the point.
Jonah was three nights in the belly of the fish, so shall the son of man be 3 days and 3 nights in the earth.
Did Jesus destroy the Power of the Grave?
Did he enter death completely to do this?
Did Jesus cease to exist for those three days?
