No, I believe that someone who is not following Christ is not a child of God.
Mrs. Edwards may be a good person but she is certainly not a follower of Christ. That is all I intended by my original comment. I have no animosity towards her at all.
For one thing, every human being has the not so proud distinction of being in her shoes if not presently, then in the past.
I understand that you have no animosity towards Mrs. Edwards. That is good.
We will have to agree to disagree on what your definition of a "child of God" is. :)
