It is often forgotten that telling people how to repent is actually more compassionate and caring than "tolerating" their sin. Today's world of luxury affords no greater sin than giving "offense." But remember, those who are not offended by the Lord are blessed, and those who ARE offended by the Lord are cursed. (Matt. 11:6) Hell may be an unpopular idea, but it's a reality. This nebulous notion that everyone eventually makes it to heaven without even bothering to change their attitude about obeying Christ is wrong. People have to repent of their wrongdoing -- no unclean thing is worthy of heaven.
In today's culture, many are willing to admit good should be rewarded, but they not only deny bad should be punished, but they deny bad exists. This is like saying we don't have a just God. The Bible clearly says that Jesus is not just merciful, but also just. (Isa. 45:21) Justice requires punishment for evil. Churches need to step away from the politically correct hogwash and teach what's in the Bible.
