The biggest lie is that they are "God's organization". All others spring from this one, because it gives them the necessary authority. The scales started falling from my eyes 1 year and a half ago, when I found out that they lied when they said that they had "restored" God's name into the N.T. by putting Jehovah in all the O. T. quotations in the N. T. But then in 3 scriptures they kept the "Lord" even though they are O.T. quotations because those 3 scriptures refer to Jesus. But nowhere do they give any explanation.
