That which opposes God is worldliness which is exemplified by the desires of the flesh, the desires of the eyes and pride in possessions.(1 Jn. 2:15-17) Furthermore, those who seek to keep on sinning are not Christians. (1 Cor. 6:9-10, Jn. 3:9) Obviously, no Christian is perfect, yet he does not seek to make a practice of sinning. In fact, the Christian puts sin to death thanks to the empowering dynamic of the Holy Spirit.(1 Cor.5:9-11)
"The cold hard truth is that most guys' struggles are only known by their fellow Christian buddies and unless Christian dudes man up and stop arguing about stupid secondary theological issues and spend their energies holding one another accountable to get dominion over their underwear, then Christian friendship is nothing more than Christian fakery."
