Understanding GOD - part 3

I have been trying to understand GOD from different perspectives. You can read my earlier posts Understanding God, Me vs Me to understand God , Understanding God - Part 2.

We generally listen about god from Theists (devotees of GOD) or Atheists (who denies the existence of GOD). I tried to observe the lives of devotees around me. There are lot of people in my family and friends who pray to god everyday.

1. Are they happy in their life? Ofcourse not. I never seen their wishlist being empty. Or is it the human nature to always wish something new?
2.  Devotees sometimes behave like escapists. They put all the failures/non-achievements on GOD's name. Instead of trying hard they will say that "God has given me only this much" and they will adjust with that.
3. Jihadis: Unfortunately big devotees are scaring the world on the name of GOD. Terrorists do prayer everyday. They kept a name for their process, "HOLY WAR". But will GOD ever tell them "Don't kill people"?
4. Indians won't forget Ayodhya and Godhra incidents, both happened on the name of GOD.

In all the above cases, I feel GOD has failed in giving WISDOM to the devotees. I'm not evaluating GOD, but I just feel devotees could think/act better.

When you think of positives:

1. GOD really gives confidence to his believers. I know many people who hold Jesus cross or start chanting Hanuman name when they are scared. 
2. Some people are afraid of doing bad things. B'coz they think GOD will punish them later. I call it utter foolishness. A person should be scared of his heart not to god. But atleast something good is happening. 
3. Its not only about god, but you really feel very peaceful when you go to some temples. That may be because of architecture, environment etc,. Or may be you feel the presence of GOD there.

I don't know what to conclude from this post. Being a devotee of god will have both positive and negative effects in life.
