God 

If used with a capital 'G', usually this is referring to the creator and sustainer of all things both living, material in nature, and spiritual.
When spelled with a lowercase 'g', the word is usually referring to a power or spirit that is less powerful than the previous mentioned "God".

Capital 'G': All glory and praise be to God most high.
Lowercase 'g': Our god Buddha will never be enough for eternal life.
