What is a lasting formula for world peace?

God says it very well—

Yet here now you can take the Five Steps to Peace and raise your consciousness, moving from concept to principle, in considering, exploring and deeply understanding life.

Should you wish to take this fast track, here again is what you must do. 

Here again are the Five Steps to Peace—

Acknowledge that some of your old beliefs about God and about Life are no longer working;

Acknowledge that there is something you do not understand about God and about Life, the understanding of which could change everything;

Be willing, for a new understanding of God and Life to now be brought forth, an understanding that could produce a new way of life on your planet;

Be courageous enough to explore and examine this new understanding, and if it aligns with your inner truth and knowing, to enlarge your belief system to include it; and

Live your life as a demonstration of your beliefs, rather than deny them.
