The time between lifetimes, or when one is dead, is a time of extreme susceptibility to programming. Imagine being asleep while someone manipulates your dream and you in it. You are simply an observer not only to what is happening around you but “your” reaction and actions in it. The environment itself is just an illusion created in someone else’s mind and the actions of those in it are often controlled by that someone or his cohorts.
Now imagine this situation lasting for a year and a half; currently about the time it takes someone to reincarnate. 200 years ago it would have taken more like 20 years. Imagine this time being spent being tortured and or raped while being taught a specific belief system; be it religious or political. Also being taught that a certain sorcerer is God.
In Genesis (Bereshit) 14; 21 – 24 (Chabad.org) The king of the conquered city of Sodom beseeches Abraham to take all the possessions (loot) from his city but to leave the souls. Abraham declines, saying he doesn’t want it to be said he got wealthy from Sodom (despite having pimped his wife for money prior). Presumably he takes the souls with him.
In Genesis (Bereshit) 23;3 (Chabad.org) After Sarah dies, Abraham “arose from before his dead” to address the people of Canaan and request a place to bury her remains.
John 8:44 Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
John 8:56 Your father Abraham rejoiced to see my day: and he saw it, and was glad.
