Ask Dr. John with Dr. John Whitcomb. Question: Please explain what the Gap Theory is and why it is not Scriptural. Question: Please explain the "olive tree" in Romans 11:19-24. I am wondering about the “grafted” branches being able to be “cut off.” Question: Can you please help me understand the qualifications for pastors in 1 Timothy 3 and Titus 1? Question: There is a position espoused at my church that takes a middle ground position on the sign gifts. The pastor is unwilling to believe that 95 percent of the reported sign gifts today are authentic—especially in places where the gospel and the church is well established, such as in the United States. He does believe that the sign gifts may be used in frontier church planting situations among the first generation of believers. Once a church matures, the greatest sign of God’s presence is love. Is there a danger in taking this position? Question: What is a good way to study the differences or similarities between the coming millennial kingdom and the Kingdom of God that applies to all saints (OT and NT) even outside of the coming thousand-year kingdom? Question: I have a friend who is being led astray by teachers who use Scripture to promise that speaking the name of Christ will bring healing. He has spent week-long seminars on retreats about this topic and it is affecting his marriage now, and his family is attending many different churches—partially because of this issue. What should I tell him? Question: What forms should we expect apostasy to take in these last days? Question: What are some of the most important lessons from the Pilgrims?
