NOTE: There were debates in regards to the identity of the 10 virgins. Some say they are the tribulations saints at the Second Coming of Christ as the next two parables in Matthew (Rapture would have already taken place by then). My interpretation is that Jesus would want everyone to be prepared, either the rapture of the church or His second Coming. The oil that the foolish virgins should have been carried along can also represent the Holy Spirit (which is quite consistent in the Bible). If that is so, then the five foolish virgins may represent those who have heard about Christ but unregenerated at the heart. Judging at their same appearance as the five wise virgins, they might even call themselves Christians. These are the ones Paul wrote, "..having a form of godliness, but denying its power" (2 Timothy 3:5).
