Mrs Smith is further along the path away from the JW's than I. I have been to a Catholic church and one or two other smaller christian fellowships, but we go to the Methodist church. It suits my personality and I feel comfortable there. Jesus was a Jew, and you cannot lable him into any specific group. Thus I am Christian, I follow Christ.
The body of Christ is spread around the globe. This makes my fellow Christians, wherever they go and worship, my family.
You don't spend all your time in a building or church. You live and work and walk every day with Christ. I feel that is what makes you a Christian. Not where you spend a few hours every week.
