"Later I thought do you want your children calling you by your name or do you want them to say dad or mom or father or mother."
I thought moomanchus point was quite interesting. Think about all the times jesus prayed to God. He always refered to him as "Father" (John chapter 17, Matthew chapter 6, His prayers in the garden of gethsemane). He always spoke about his "Father". Just as a child would refer to his own Father as Dad, papa, Father such was the closeness of their relationship.
Jesus is our example to follow. Shouldn't we also be praying in the same way, when speaking directly to him (jehovah / yahweh) as "Father" which would show a deep reverence toward him in that we are his children. This would make sense considering the fact that we dont exactly know what his proper name is.
