Why is Gospel not sufficient?

Honestly, I do not have a clue. It is enough for me, it is enough for the people in my church, it is enough for my blogging Reformed brothers and sisters in Christ... But it is not enough for many post-modern seekers and church innovators. For them Gospel is simply too old-fashioned, and all that talk about sin and repentance too depressing and too gloomy.
A lot of research is being done in the area of church growth, as if chasing after numbers were superior to preaching the Gospel. Modern church, they say, should be seeker-friendly, attractive, kind and well-anchored in the culture. What they advocate is not telling sinners that they are sinners. Despite the sound and cautious words of reason spoken and written by the great men of God of today the temporary popularity is what is on nowadays. Despite all the warnings uttered in the subject of Emerging Church and its leaders, Brian McLaren is gaining on popularity every day here in Sweden. His ideology is attractive to the culture that has been depraved of the real gospel for many, many years. And, of course, it is better than atheism, but it is deceiving people into a false peace of soul.

When I first started blogging, I began to learn about all those apostate trends in the Church, but was regarding them as geographically distant and theoretical for my corner of the world. Oh how wrong I was, and how naive. Many articles read since then have been good eye-openers to the inconvenient truth about the true state of the Church everywhere.
Why does my mother choose to still stay in the Roman Catholic church? Not because she shares the beliefs completely, but because the rituals are attractive, the decorum is captivating to the eye, the rich human tradition makes it hard to break the ties. She approves of my conversion, she finds no doctrinal flaws in the Biblical Gospel, but as far as she is concerned, things shall stay where they have always been.
Why do some people in my in-law family choose the flashy sparks of spiritual fixes served by Pentecostalism? Their explanation is similar to my mother's: they have never taken time to examine the validity of the doctrine, they have just accepted it without questioning, in spite of many signs of warning along the way.
Why do young people turn in the direction of New Age? Well, because, to answer it in a simple way, it offers something the materialism does not offer.

A digression: Christmas in Sweden is a period of two days, December 25th and 26th. The second day is for many a golden opportunity to go to the shops and hunt for bargains. This year was no different, in fact, and, according to media, it was almost impossible to find a parking space at the big shopping centres in town, and people were like crazy in the shops, fighting for stuff.
Is this Christmas?

So no wonder many young people turn away from this, and towards New Age spirituality, because it is so all-inclusive, easy and forgiving, often showing fast remedies to their problems.
Christianity is simply too difficult, too fundamental, too demanding. The modern man's religion must be easy and convenient, may cost a little money, but must pay back immediately. No way the modern man is going to wait for his reward until after his death. Such morbid notions belong to the Middle Ages, and people who preach Jesus crucified are not welcome into the modern man's feng-shui house.

Why these bitter words today? Well, I came across a Swedish blog criticising John MacArthur and his preaching directed against the emerging apostasy. Gospel according to Jesus is not appreciated by a modern man, to the extent of lies and straw men creation, because it hurts to hear the truth.

For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart. And no creature is hidden from his sight, but all are naked and exposed to the eyes of him to whom we must give account.
(Heb 4:12-13)
