The 10 virgins are bridesmaid. They are NOT brides to the groom. It was devasting because they could not fulfil the role they were were supposed to play. The characters are used to convey the story of the certainty of the wedding. In interpreting the parable, we are not to allegorise the parable (like the lamp means this and the oil means that) - because all parables carry a central message and a main thrust. (The school of allegory belongs tot he times of Oriegen that follows the school of typology. )
The central thrust of the parable is this:
The Kingdom of God is coming with all certainty. We must be prepared like the 5 prudent virgins. The essential consequence is that those who are unprepared will miss the boat - hence will not enter the Kingdom of Heaven.
The Kingdom of Heaven refers to the sovereign reign of God here on earth and also eternally in Heaven. Only those who believe in Jesus Christ, the promised Messiah will enter the Kingdom of God and will be counted as the SAVED. Salvation is only in Jesus ALONE! We are not saved by our titles or respectable religion but only on our trust in the Lord Jesus.
Jesus saved us from the penalty of sin because sin is cupable. Here is 3 basic Steps in entering God's eternal kingdom.
"Dear Lord Jesus, I am sorry that I have greviously sinned against you. Please forgive my sins and wipe away all my trangressions. (1 Jn 1:9 says that when we confess our sins, God is faithful and just to forgive us our sins and cleansed us of all unrighteousness.)
"Please take full rein of my life. Please enable me to live with a sense of God in my life so that I will transfer alll my trust in you. Please give me your guidance how to live a life worthy- that I may be your disciple."
3. "Thank You"
"Thank you for your saving grace, so that I do not need to face the eternal damnation of hell. Thank you for leading me into your kingdom."
