as far as free will, we have virtually none as an active witnesses. If we do not agree 100% with the WT party line, we better keep our mouth shut!
May I suggest that it is the sin nature rather than the absence of free will that keeps you and certain of your dissenting family members in bondage to a silly little cult? If you were born of God, it would be impossible for you to live a lie, that being against your new nature.
True, there may be short term consequences like shunning. But God will give you weapons to actually fight the enemy, instead of just feeding the monster in hopes of him being placated and leaving you alone in your misery.
So, even in our bondage to the sin nature, God hasn't left us without choice. In Jesus Christ and especially the HOLY SPIRIT, God has restored a Free Will of sorts to man.
When a person has had enough of the weakness of sin, I highly recommend trying out the POWER OF GOD.
