If there is no personal Judgment after you die, then Jesus' sacrifice is meaningless.
The WT seeks to destroy this truth several ways:
1. Your soul is not conscious of anything after you die - even though Rev. 6: 9 reads otherwise:
When he opened the fifth seal, I saw underneath the altar the souls of those slaughtered because of the word of God and because of the witness they had given. They shouted with a loud voice, saying: “Until when, Sovereign Lord, holy and true, are you refraining from judging and avenging our blood on those who dwell on the earth? - NWT
2. You get a clean slate just by dying (Opening Post Subject)
3. Jesus didn't die for you personally; He died for Adam - This is in spite of WHO the bible says Christ died for:
The one who did not know sin, he made to be sin for us [Not Adam], so that by means of him we might become God’s righteousness. 2Cor. 5 (NWT)
4. They teach that we are living in Judgment Day Now - This in spite of the fact that the Bible says you get judged AFTER you die:
"it is reserved for men to die once for all time, but after this to receive a judgment" - Hebrews 9: 27 (NWT)
