What Makes God, God?

Isaiah 40 verse 18, To whom will you liken God? Or what likeness will you compare to him? The obvious answer is no one, nothing. Why because God is God and he is in a different category as the Creator, transcend above his creation. God is One, an undivided essence yet shared by Father, Word/Son and Holy Spirit. God has attributes which are shared in some measure with humans, his marred image bearers such as love, mercy, kindness but God also has characteristics which are his alone that can not be shared with any. This incommunicable attributes are unique to God!
