I said "Christians" .. so you are not alone. 
Anyway, I won't just criticize and leave it at that. My criticism
towards you might be harsh, but I try to make sure it is
constructive.
I have something to share with you:
http://www.pbs.org/empires/thegreeks/characters/socrates_p4.html
After his service in the war, Socrates devoted himself to his
favorite pastime: the pursuit of truth.
His reputation as a philosopher, literally meaning 'a lover of
wisdom', soon spread all over Athens and beyond. When told that the
Oracle of Delphi had revealed to one of his friends that Socrates
was the wisest man in Athens, he responded not by boasting
or celebrating, but by trying to prove the Oracle
wrong.
So Socrates decided he would try and find out if anyone knew what
was truly worthwhile in life, because anyone who knew that would
surely be wiser than him. He set about questioning everyone he
could find, but no one could give him a satisfactory answer.
Instead they all pretended to know something they clearly did
not.
Finally he realized the Oracle might be right after all. He was the
wisest man in Athens because he alone was prepared to admit
his own ignorance rather than pretend to know something he did
not.
