From A.W. Pink's The Attributes of God, on God's solitariness:
He is solitary in his majesty, unique in his excellency, peerless in his perfections. He sustains all, but is himself independent of all. He gives to all, but is enriched by none.
When my husband and I were brainwashed taught with Gary Ezzo parenting material, we were told to tell our children what it meant to give glory to God. It was to "make God bigger."
I don't think Pink would have agreed.
