The message they preach eliminates the possibility of Jesus being the Mediator for a member on Judgment Day, and they teach that virtually no one can have Jesus as their Mediator after 1935. So, they discourage current members from claiming this Christian offer from the Lord.
As a result, the religion is built around willpower to do what is right as opposed to being declared righteous (justified) by grace through faith. Even though Isiah. 64: 6 declares:" all our righteousnesses are as filthy rags", they still believe their good works (passing out literature) will save them.
They teach that Justification is no longer available. So, there really isn't much in the NT that applies with that kind of restriction. ,
Hope that answers your question.
