Why do we have sharply divided views? Why are we different in our reasoning? Why is it that while some people deeply believe in God, some don't believe that He exists?
The answers to all these are simple. It is because the almighty God made (and still makes) it so. Right from the begining, God has always been the epitome of varieties and dynamics.
Does this mean He is an author of confusion? NO. All the dynamics are what made God ALMIGHTY.
For humans, we can overcome our differences through understanding and tolerance. God indeed asks us to show love and kindness to others. Depite our numerous differences, we can still live in unity and peace.
