It has been my experience that jw' s have no concept of salvation in the traditional Christen viewpoint.
It has also been my experience that a jw will not discuss or entertain the mere concept of 'salvation'.. And in no way willl they accept any 'salvation' through or because of Jesus Christ.. In fact, my jw will prefer to run away than to have this conversation, go hide in bathroom, need to answer phone, need to answer neighbor he neglected for months on end , etc......I think he would prefer a tornado than do have an actual discussion.
And, for goodness sakes, never, ever, find youtubes or museum, college, academic, etc... that might negate their beliefs.
