Vanderhoven7 is correct. It is a truth I did not come to know until after I stopped being one of Jehovah's Witness. I believed that Jesus' ransom sacrifice was for all humans as it is written at John 3:16.
After I stopped being one of Jehovah's Witnesses I learned directly from Watchtower publications that Jehovah's Witness are taught that Jesus' ransom sacrifice is only for 144,000. The Watchtower teaches that if you are not part of the 144,000 your only hope for salvation from eternal death is to align yourself with those of the 144,000 who are left on Earth. Later, that doctrine was updated to state that our only hope as non-Annointed ones was to be loyal to the Governing Body.
In an indirect way, the Watchtower teaches salvation for the Great Crowd comes through the Governing Body and not Jesus. Again, the Watchtower does not directly make this statement, but it is a logical conclusion based on the Watchtower's publications and statements made by the Governing Body on JW Broadcasting.
