Power of Thought

The thought of god has always been a battle between science and faith. When does the human race rely on god or on themselves. We have always prayed on the gift of knowledge, but when do we use it. My biggest problem in my own mind is, am I be lazy if I constantly use prayer instead of the knowledge that I know I have. Could it be a sin not using what we have been giving, I may never know. Just a little thought I think about. What do you think?
