I agree with SixofNine.
I would suggest you not base your argument on the doctrine of JW's or other religions. For me, it is a faith issue-do I believe that Jesus Christ is Lord? Do I believe God rasied him from the dead?
Read Romans chapter 10, specifically verses 5-13. (And I would suggest you try to read other versions besides the NWT)
To answer your questions though, I can say that we as a congregation (Baptist) do most of our "preaching" not so much by door-to-door but by ministering to those who need help. Reaching out to the lonely, visiting the sick, feeding the hungry, helping people pay their bills or buying groceries,etc... We do some door-to-door but it is not our focus. I can say that our denomination has about 5,000 missionaries in about 153 countries and about 5,000 in North America.
I myself was able to go to Moldova in 2000 (having never flown in my life before!)and be a part of a Medical team where we went from village to village giving out medicines and vitamins, money, whatever we could. It was one of the "richest" experiences of my life!
I believe that our souls are immortal and that when we die we are either present with the Lord or not based on whether we have accepted him as our Savior or not. (2 Corinthians 5)
But, again the real issue is Jesus. Don't lose your focus on him-people who are Christians will fail you, not every church will be a good represenative of Christ, not every "Christian" will be either.
I know how hard it is, I have been where you are! To be honest I was scared to death the first time I set foot in a church after I left-which was about 9 months or so, a Catholic church. I was so indoctrinated.
Anyway, this is my 2 cents worth to this topic!
Peace to you!
