I am not a Jehovah's Witness but feel compelled to answer this question. I think for the most part your going to get answers that say they are not afraid to die. Somehow, I do not think that is correct. I think, in each of us there is this will to survive to live and not to die. Now we know that we will all die. But when the time does come, and I have seen my share of death, there is a certain part of us that is scared of the unknown. Even though we have our faith and I most strongly believe in Jesus Christ and what he has done for me. Now faith is confidence in what we hope for and assurance about what we do not see. It is by faith that we have our salvation and eternal life but this is an assurance of what we can not see. And there is s little part of me that asks, am I right in the way I am thinking? My answer is I think so, but a very small part of me questions this which keeps me in line and keeps me in his Word and studying his words, so that when my time comes I will feel pretty confident and not be so scared. But being a little scared is, in my opinion, a good thing, it keeps us from doing stupid things.
