The "virgins"--a title of purification connoting their eligibility as Christ's future Bride--are all believers (2 Timothy 2:19), and thus have "light" in their "lamps", which elevated lamp is the "spirit of their mind", as Ephesians 4:23 and Proverbs 20:27 conjointly tell us.  And that "Light" in the lamp of their minds is the Word of God, is truly Christ, Who is the "Light of the world" (John 8:12) and gives Light to all those who draw near to His illuminating Truth (Matthew 5:14-16), just as Christ told the Pharisees that they were happy, albeit "for a time", to bask in John the Baptist's light, while they had it (John 5:33-35), who preached of the True Light--namely of Christ (John 1:6-9, 19-30).  The Holy Spirit is the oil, which sanctifies (Leviticus 8:10-12), just as oil functionally does,--(it being an anti-fungal and anti-bacterial and anti-viral agent [Luke 10:34])--; and which was, as we know, Biblically used for anointing kings, prophets, and priests, and holy articles; and which, moreover, in direct relation to this particular parable, naturally sustains the flaming Light of the Word that has been lit in the lamp of the listener's mind.  The "foolish virgins" or believers are like the stony ground that has no Root in it (Mark 4:16-17; 1 John 2:18-19; Revelation 22:16; John 15:5-8), being those who have "believed in vain", to use Paul's words (1 Corinthians 15:1-2; John 12:42-43; James 2:14-17), which corresponds to them having no Oil in the lower "vessels" of their bodies, which is to say having not the Holy Spirit; and thus they are not known by God, being none of His, as Paul says, for not having His sanctifying Spirit within them (Romans 8:9, 13-14).  They are thus ever in danger of having their Light "go out", in hard times (Matthew 25:8).  All the virgins or believers "sleep" just as the disciples slept in the garden, (to which nocturnal incident the Second Coming is analogous), due to Christ briefly being taken away from His disciples about a stone's throw, as Luke says (Luke 22:45; Matthew 24:9-12), because believers and their church ministries belong to "the day", as Paul speaks symbolically to the Thessalonians, and not to "the night" (1 Thessalonians 5:4-6); and the disciples therefore temporarily slept only to be awakened by Christ's return, because that intermediary period of "sorrow" was the "hour and the power of darkness", as Christ there told them (Luke 22:52-53; Psalm 2:1-2; Revelation 17:12-14; 13:7), "when no man can work", as He further informed in the gospel of John (John 9:4-5; 2 Thessalonians 2:3-8; John 17:12).  Thus, when the disciples awake, it is therefore only at the return of Christ, before Whom, being roused by the sound of His voice, they immediately "rise", and to Whom they go, at the Mount of Olives (Luke 22:39, 45-46; 1 Thessalonians 4:16; Zechariah 14:4-21; Job 19:25-26), there to be gathered with Him (Matthew 13:30; Revelation 19:11-14), right when the "multitude", who had themselves previously been gathered, similarly comes forward, however only to oppose Him (Luke 22:47-48; Revelation 19:19-21; John 18:3-6); these rebellious troops being prophetically led by "the son of perdition" (John 17:12; 2 Thessalonians 2:3-4), who acts "deceitfully" and with "flattery" (Luke 22:47-48 ; Daniel 11:21-23,32).  However, whereas Judas, the betrayer, is, in some sense, successful in leading his insurrection, the Anti-Christ, (of whom the former serves as a small-scaled antitype), is most decisively not (John 18:4-6; 2 Thessalonians 2:8); at which final armageddon, "the foolish", among Christ's church, who do not have the Spirit of Christ, but who merely called Him "Lord", which is to say "Master", and who listened to His preaching but hypocritically did not obey Him, proving themselves disloyal (Matthew 7:22-23, 26-27), like the young man among the disciples whom we see fleeing naked during the foreshadowing evil hour (Mark 14:51-52); these are rejected for not being known by Him, for not being clothed in His righteousness (2 Corinthians 5:2-3; Revelation 19:7-8; Matthew 22:11-14).  And "the wise" (Matthew 7:24-25), who have been made wise by Christ's indwelling Spirit, which searches out the deep things of Christ, as Paul said (1 Corinthians 2:10-16), are gathered, like the twelve disciples were, with their Lord, however this time triumphantly so, to meet with Him in the air and in the clouds (1 Thessalonians 4:15-17).
