There are a litany of gods out there.   Yes, I know that there is only One True And Living God but not everyone is addressing this God.   

Do we assume that among this litany of gods that the True And Living God knows that we are talking to Him?   

Have you ever asked a question in a group of people and someone asked: "Are you asking me?"

How do you avoid the confusion which causes these questions to come back to you?   

You address the statement or question to a specific person.   

When we pray, we are to pray to the Holy Spirit Of Christ Jesus using His name: Jesus.   

By doing so several things are accomplished:
   ➛ it is clear who you are talking to
   ➛ it honors Christ Jesus
   ➛ it honors the Holy Spirit Of Christ Jesus
   ➛ it gets results

God is just the generic name for the Supreme Being.   It is not that deity's name and should not be used in prayer as it is NOT specific.
