Christianity on the verge of mive collapse(in few decades) or the birth of a new modified one?

I have to agree with you. The Bible specifically talks about the great falling away. This refers to his people not unbelievers. The Church has become lax and has allowed the world into their churches. The problem is that we stress so much about forgiveness of sin, that many believe that they can do whatever they want and expect forgiveness. This is not what the Bible teaches. Repentance is stressed over and over again. Repentance doesn't mean to be sorry for what you do, it means that you truly feel so much anguish that you stop doing it. We also have allowed ourselves to be politically correct. We worry so much about hurting others feelings that we compromise the true teachings of Jesus. Forgiveness of sins is just the tip of the iceberg of what the Christian life is about. When we pursue fame and fortune instead of his will for our life, we are just asking for trouble.
