JW's share a belief which most Christian denominations teach - heaven awaits! (at least for 144,000)
(Matthew 20:28) ...the Son of man came...to give his life as a ransom in exchange for many.”
What does a 'ransom' normally achieve?
(1 Timothy 2: 6) Christ Jesus, who gave himself a corresponding ransom for all.
Corresponding to what? If Adam had not sinned, what were the prospects for all/some of his descendants? King/priests in heaven?
Can a ransom ever buy back more than what was lost? If Jesus' ransom did, how could it 'correspond' to what Adam lost?
