This realization can sometimes be disheartening and looking back can almost hurt at times.
Today I was reading a book by Rob Bell and even if I don't agree with everything He has ever said, he made a great point. He said that without us being where we where, we would never be where we are today. Basically, if I hadn't had the wrong understandings, there is a chance I wouldn't have the greater understanding that I have today.
To me, that seems true. That's how our life is. Sometimes we have to go through things to learn our lessons. We have to experience being wrong to know what is right. That is part of the beauty of who Christ is. He is the right in our world of wrong. He shows us truth in a world full of lies. In other words...He is who He says He is....the light unto our path.
On somewhat of a side note, I found this video rather interesting. It's short and really resonates with me.
