Well, you see, there are some that would have you think that once you become a Christian that it doesn't matter how you live, you will be raptured because you said the sinners prayer. Once saved allways saved. None of the  parables or warnings given to in the New Testement have anything to do with Christians, they are being given to non believers. Therefore, why waste your time fasting, why waste your time studying the word, etc. Go out and live it up!
 
Are you realy foolish enough to believe that?
This is why many Christians who have foolishly accepted this arguement will not be raptured.
This is why anyone who teaches the same will be a target of their wrath, after the rapture.
This is a carnal gospel, changing the gospel to please the flesh, the sinful desires.
 
Please heed the warning in Romans 12
 
1Therefore, I urge you, brothers, in view of God's mercy, to offer your bodies as living sacrifices, holy and pleasing to God—this is your spiritual act of worship. 2Do not conform any longer to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God's will is—his good, pleasing and perfect will.
