Consider the following words of Jesus:
21 “Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but only the one who does the will of my Father who is in heaven. 22 Many will say to me on that day, ‘Lord, Lord, did we not prophesy in your name and in your name drive out demons and in your name perform many miracles?’ 23 Then I will tell them plainly, ‘I never knew you. Away from me, you evildoers!’" (Matthew 7:21-23, NIV)
When I was growing up, I read these verses under the impression that the people Jesus was talking about included "charismatics" and modern-day "faith healers." The Christian leadership I was under at that time painted a dim picture of the motives of modern-day miracle workers, pointing to this verse as just one evidence that "miracles" are usually associated with false teachers. But when I was reflecting on these verses yesterday, I had a much more chilling thought that hit a lot closer to home.
