Matthew 25:1-13 ... Then shall the kingdom of heaven be 
likened unto ten virgins, which took their lamps, and went forth to meet
 the bridegroom. 2 And five of them were wise, and five were foolish. 3 
They that were foolish took their lamps, and took no oil with them: 4 
But the wise took oil in their vessels with their lamps. 5 While the 
bridegroom tarried, they all slumbered and slept. 6 And at midnight 
there was a cry made, Behold, the bridegroom cometh; go ye out to meet 
him. 7 Then all those virgins arose, and trimmed their lamps. 8 And the 
foolish said unto the wise, Give us of your oil; for our lamps are gone 
out. 9 But the wise answered, saying, Not so; lest there be not enough 
for us and you: but go ye rather to them that sell, and buy for 
yourselves. 10 And while they went to buy, the bridegroom came; and they
 that were ready went in with him to the marriage: and the door was 
shut. 11 Afterward came also the other virgins, saying, Lord, Lord, open
 to us. 12 But he answered and said, Verily I say unto you, I know you 
not. 13 Watch therefore, for ye know neither the day nor the hour 
wherein the Son of man cometh.
  
  Mark 8:34-38 ... And when he had called the people unto 
him with his disciples also, he said unto them, Whosoever will come 
after me, let him deny himself, and take up his cross, and follow me. 35
 For whosoever will save his life shall lose it; but whosoever shall 
lose his life for my sake and the gospel's, the same shall save it. 36 
For what shall it profit a man, if he shall gain the whole world, and 
lose his own soul? 37 Or what shall a man give in exchange for his soul?
 38 Whosoever therefore shall be ashamed of me and of my words in this 
adulterous and sinful generation; of him also shall the Son of man be 
ashamed, when he cometh in the glory of his Father with the holy angels.
