No Sin?

I finally figured out why Christianity has taken such a nose-dive in the past 25 years. Very little mention or teaching about sin. Because so many were hurt by legalism, churches have gone to the other extreme. Now all you have to do is "receive Jeuss", or "follow Jesus," or some such thing, but no mention of repentence, confession of sin....nada. That brings up the very interesting question the Young Calvinists keep asking. Are people who "receive Christ" without repentence truly born-again Christians? Is that perhaps why the church is so fleshly and worldly? It's an interesting thought.
