Was there a time when they were not evil? According to the bible....the evil slave was not ALWAYS evil."
I sincerely believe that the Watchtower Society since it's foundation to this day has been questing/searching for Jehovah God. Because of their yearning to Find and to Know the True God, Jehovah God listened to these teachers and to those who yearnestly searched for Him. God with His Loving Kindness and Compassion for these ones, Jehovah God assigned these ones to be God's representatives here on earth to teach the accurate Word of God, His Will to the peoples of the whole earth; and God lovingly gave the Watchtower Society His acceptable version of The Bible. I sincerely believe that The New World Translation Bible published by the Watchtower Society is an accurate revision; and I personally trust it and consider this Bible as being the true accepted version that Jehovah God Approves for teaching all peoples.
One looking/studying The Watchtower's Teaching history records, will find that the Watchtower has failed to teach us, God's people, with God's Word of Truth contained in His Holy Book, the Bible; as well the Watchtower Society has failed and continues to fail when it comes to applying God's Principles: Teaching God's Peoples' with God's Principles only and Conforming to these only!
Disconcerted teachings, Unscriptural teachings have been accepted by the Society as Biblically and Scripturally acceptable.The Watchtower Society as well has innumerated God's Laws : created these 'laws'' independently from God, and made them their OWN! And they utter them by saying that they came from the Mouth of God! I will give you one example here: The 1935' Doctrine: grossly, doctrinally innacurate and still taught by the Watchtower Society today as "God's Truth Revelation".
The Watchtower Society was never an evil slave class in the sense that Jehovah God gave the Watchtower Society His Word the Bible. These teachers have failed to provide God's children with Spiritual food necessary for our salvation. They made the Word of God invalid by their own traditions, implementing dogmatic views to peoples' lives - with serious consequences that have resulted in loss of human life, thus making them guilty of disregarding God's precious Laws of Preserving Human LIfe alive!
PSALMS: 50:16:" But to the wicked one God will have to say:" What right do you have to enumerate my regulations, And that you may bear my covenant in your mouth?."
ACTS 17:11" Now the latter were more noble-minded than those of Thes-sa-loni'ca, for they received the word with the greatest eagerness of mind, carefully examining the Scriptures daily as to whether these things were so,"
