Compassion, love, discipline, sacrfice is what being a Jehovah's witness is truly about. As Christians, it is our wish to emulate our loving Leader Jesus in his ways, and he personified those qualities.
And when you say every religion has failed, and none have brought real enlightenment, real understanding, this is simply not true at all. Jehovah's witnesses have been for quite some time now enlightening people about truths of the bible, to help them sway away from philosophical views of the bible, which always fall short of the author's theme of his own book.
And if spirituality does not care about the book as you say, why would you ever at anytime refer to the book for "spiritual growth and encouragement" as you said in the first paragraph of your last response? You say God bless, yet you don't believe in God's book? How can you truly be spiritual, if you deny the one who provides spirit for you to abide in?
