Speed of change seems to be determined by the speed of idea distribution.

With the presence of the internet, namely social media, ideas travel faster; and because of that so does trends and philosophy. We moved from a trend of atheism to now it being no longer a trend, now spirituality is being renewed.

Examples of ideas/movements that came and went:

  - Christendom: Emerging church, now we have "Progressive Christianity" and New Age

  - American Religion: Atheism, now we have Eastern Paganism or Non-Christian Spirituality

  - Culture: Post-modernism, now its neo-modernism or Post-Christianity

  - Science: Classical Darwinism, now Neo-Darwinism, next it'll probably be some form of panspermia

In the end, what will remain is God and His word (Matthew 24:35).

Change is happening fast.. Will you keep up?
