One would think, if it was so important to Christian doctrine, that God would have been a little clearer on this when he wrote the Bible. I will now demonstrate that the whole "ransom" idea is a man-made invention (specifically, the Catholic Church but that's for another thread):
Then Jesus said to his disciples, "Whoever wants to be my disciple must deny themselves and take up their cross and follow me. For whoever wants to save their life will lose it, but whoever loses their life for me will find it. What good will it be for someone to gain the whole world, yet forfeit their soul? Or what can anyone give in exchange for thier soul? For the Son of Man is going to come in his Father's glory with his angels, and then he will reward each person according to what they have done.
"Truly I tell you, some who are standing here will not taste death until they see the Son of Man coming in his kingdom." ~Matthew 16:24-28.
It's quite obvious to me that the cross and Jesus' death was a metaphor describing something that we ALL have to do to be his followers: Deny ourselves, take up the cross, and lose our life to save our soul. If this means that we all have to be physically crucified, then not one of us can truly be a disciple of Jesus.....EVER. The whole story of Jesus is a parable that describes what we have to do to enter the kingdom: Stop being selfish and learn to serve others, and to do it from the heart and not under compulsion, for the common good of all including ourselves. This is the result of recognizing that we are all ONE.
This is the key: SOUL = CONSCIOUSNESS
The Dalai Lama and many others speak the truth. Selflessness is the key to ascension and an awakened consciousness, and this can now be scientifically demonstrated.
All of this was lost when the Catholic Church literalized these Savior stories so that the masses would believe they were worthless born sinners that are powerless to change the world without their historical Jesus coming back to save them. This has led to 2,000 years of spiritual darkness and collective impotence.
Additionally, Jesus was teaching the Law of Karma: you reap what you sow, and what goes around comes around. There is no "defined line" between eternal life and eternal death. Especially when one measly lifetime is all there is to go on. Judging a person's eternal fate based on one lifetime when we all come into this world under vastly different circumstances and there is no level playing field? That never made any sense to me and never will. We all simply have to keep doing this physical life until we are ready for the next level up.
And last but not least: If the above verses are to be taken literally, Jesus was a liar who told his disciple that some of them would survive to see him return and would see the kingdom. If that return was a personal experience, then he wasn't lying.
