"Jesus sacrificed something with his life that corresponded exactly to what Adam had forfeited through his sin."
Der Wachtturm, 1 March 2008, page 6
The above quote from the Watchtower doctrine says that Jesus' redeeming sacrifice is effective only in relation to Adam's sin. The sin that every person personally bears is not covered by Jesus' salvation. The purpose of this limitation of Jesus' effectiveness is that Jehovah's Witnesses are dependent on balancing their sins with preaching ministry and loyalty to the Watchtower Society.
There is a teaching in the Watchtower Society that Adam himself is not saved by the redeeming sacrifice of Jesus because he had sinned as a perfect creature. So since it is stated in the above doctrine that no man benefits from the redeeming sacrifice because it only corresponds to what Adam had forfeited, even Adam himself is taken out of this redemption. Here we see the tactic with which Jesus is to be made completely meaningless. On the one hand his redeeming sacrifice is limited only to Adam, on the other hand Adam is also taken out of this work of salvation. Jesus can no longer be made more senseless.
If we then consider that Jesus, according to the teachings of the Jehovah's Witnesses, was actually executed as the second God, rightly so, because the law says that you should not have any other gods beside me, then the complete attack on Jesus becomes visible. Whoever is executed as a lawbreaker can no longer bring about a redeeming sacrifice. But to be quite sure that the sacrifice of Jesus has become meaningless, it is additionally limited to Adam, who is then himself excluded from the effect of the sacrifice with the help of a flimsy justification.
As if to prove itself that the Watchtower Society is an anti-Christian organization, in "The Watchtower, March 1, 2008" on page 7 it bestows a nested sentence that says exactly the opposite of what the reader expects.
Today only a few people are fully aware of the great sacrifice our Creator and his Son have made for their salvation, and that is why they are not grateful for it.
Der Wachtturm, 1 March 2008, page 7
The few people to whom the victim is completely clear are not grateful for it! What a nice example for the true intention of the old men from Brooklyn. They turn the Creator and his son into two gods to whom no one thanks. And in the Anti Last Supper, in which Jehovah's Witnesses demonstratively reject bread and wine, the Watchtower doctrine shows its full effect. Jehovah's Witnesses reject Jesus.
