For every action there is a cause and for every action there will be a reaction to another action like a wave passing across a pond or like a sound wave passing through the air.
The actions that we do in our lives are simply reactions to things that happen to us.
Therefore, mankind is like unto a sea tossed to and fro by the waves of the external circumstances of their lives.
Hate begets hate, anger begets anger and war begets war.
Only God, by motivating the hearts and lives of those who know Him,
can stop the vicious circle of violence that keeps passing back and
forth like a wave through all of mankind.
