I notice quite a few writers (mainly Christian writers), always capitalizing the word God, even in sentences where, to me, it doesn't make grammatical sense.
For example: "God is a good God"; I do not feel capitalizing "god" in the second instance is necessary, and would be comparable to something like:
"The Ghost Train's biggest liability was being a Ghost Train".
In the second sentence, capitalizing "Ghost Train" the second time is incorrect.
So, is it gramatically correct to always capitalize "God" when referring to the Christian god?
