I believe in the premillenial, pre-tribulational coming of Christ for all of his church, and to summarize that, your first poll, do you believe Jesus coming the second time will be in the future, I would vote yes with the 59 percent and with Billy Graham and most evangelicals.
The second question, you asked, "Do you think he is coming in your lifetime?" I would vote neither yes nor no. I would vote I do not know, because Jesus said, "No man knows the day or the hour." So the bottom line is, I believe that we ought to be living every day as though this is the crowning day. But we should also be planning and working with the next generation in mind, because we do not know.
