God's last name

"Aunt A, what is God's last name?" questioned Little J.
"I don't know." I replied
"Will you write it on your blog and tell people to message you if they know the answer."
"Sure. I can do that."

next day......

"Aunt A, don't forget to ask the people on your blog if they know God's last name."
"I won't forget."
"Make sure to tell them to message you with the answer. And then tell me what they say."
