Why are most Christians giving into the world ?
they are blindly accepting new age ideas (yoga, meditation based on buddhism, karma) they think loving everyone is more important that preaching Jesus is the only way to heaven. This is the falling away the bible describes will happen in the endtimes.

Even Christian music is now dominated by rock bands (gross darkness), coarse music in which people are complaining about their lives instread of rejoicing in the LORD and singing with JOY (what the angels did when God created the earth).

(And later...)

"what are you whining about? would you have every book in the world burned aside from your bible?"

yup. the bible says "Neither is there salvation in any other: for there is NONE OTHER NAME under heaven given among men, whereby we MUST BE SAVED".
