Study Watchtower, p. 10 par. 6 - "A ransom is a price that is paid to buy something back. (True!) When he sinned, he forfeited the prospect of everlasting life not only for himself but also for (nearly) all his children. (True!) In order to buy back what Adam lost*, Jesus offered his own perfect life as a sacrifice. (True!) At the time of his death, Jesus’ perfect life corresponded exactly to the life Adam lost." (True!)
*Despite these Biblical facts, the org dismisses them all with their narrative that Jesus' life exceeded the value of Adam's life and will generously promote 1000's of Adam's descendants to the status of immortal, Melchizedek king/priests! (no mention of this huge anomaly in the article, though) 🤣
