In responce to Wren's comments,
What Thomas Edison said is irrevelent on this topic. What the Word of God says is. 
Without knowledge of God's Word, guess 1/10 of 1% knowledge would be about right.
Yours,

STILL---not one verse of scripture for a pre-trib rapture. The challenge still stands.
 We will be Raptured before the Tribulation as our reward for being faithful to Jesus.    
1Th 5:9   For God hath not appointed us to wrath, but to obtain salvation by our Lord Jesus Christ,          
1Th 5:10   Who died for us, that, whether we wake or sleep, we should live together with him.          
1Th 5:11   Wherefore comfort yourselves together, and edify one another, even as also ye do 
 Only the unrighteous will be left to God's Wrath.    
Rom 2:5   But after thy hardness and impenitent heart treasurest up unto thyself wrath against the day of wrath and revelation of the righteous judgment of God;          
Rom 2:6   Who will render to every man according to his deeds:          
Rom 2:7   To them who by patient continuance in well doing seek for glory and honour and immortality, eternal life:          
Rom 2:8   But unto them that are contentious, and do not obey the truth, but obey unrighteousness, indignation and wrath,          
Rom 2:9   Tribulation and anguish, upon every soul of man that doeth evil, of the Jew first, and also of the Gentile;      
Col 3:4   When Christ, [who is] our life, shall appear, then shall ye also appear with him in glory.          
Col 3:5   Mortify therefore your members which are upon the earth; fornication, uncleanness, inordinate affection, evil concupiscence, and covetousness, which is idolatry:          
Col 3:6   For which things' sake the wrath of God cometh on the children of disobedience:     
1Th 1:10   And to wait for his Son from heaven, whom he raised from the dead, [even] Jesus, which delivered us from the wrath to come.
