I believe we should always focus on GOD in our relationship with him.
I used to think that faith is false becoz how men behave even after they believe in Christ. Crusades, inquisitions, burning of heretics...all these only showed the flaws of men, whom in wanting to satisfy their own egos, did atrocities in the name of GOD.
Sometimes I feel we become theologians rather than real christians, trying to figure out the faith from our own perspective and failed miserable. I believe every man has a different relationship with GOD. There is no one kind of relationship that fits u and fit all the others.
But one thing is for certain: Faith. Focus should always be on building our relationship with GOD and not anything else. By focusing on the flaws of men, we lose faith easily and even tend to repeat their mistakes.
