My limited understanding:
Through sinning or falling out of favor with God, the first human pair, and by extension the whole human race, was condemned to a life of despair, ending in death. This was due to the influence of a certain Evil One.
Redeem - Jesus of Nazareth, the Christ, chose to Redeem or buy us back from the Evil One's hold.
Ransom - Jesus of Nazareth, the Christ, paid the price or Ransom for this redemption with His Life.
First Adam sold himself and us
Threw everyone under the bus
Second Adam came to redeem
Those who choose to be on His team
He paid the price with His own life
As a loving husband would for a wife
This may all seem needless and foolish
But, it is God's way for evil to abolish
The WT teaches that Adam and Eve sinned willfully; therefore the Ransom doesn't cover them; no redemption, no resurrection.
I do not believe this teaching.
