It seems to me that most of us do not have a clear picture of who the God we worship is. If you asked ten Christians who God is, you are likely to get ten different answers. Therefore, it is reasonable to assume that we all have debatable notions of who God is.
But, if the patriarch and former Shepherd, David were still here he would paint a clearer picture of who God is. Here is how David described God:
The Lord is my shepherd; I shall not want.
2 He maketh me to lie down in green pastures: he leadeth me beside the still waters.
3 He restoreth my soul: he leadeth me in the paths of righteousness for his name’s sake.
4 Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me.
5 Thou preparest a table before me in the presence of mine enemies: thou anointest my head with oil; my cup runneth over.
6 Surely goodness and mercy shall follow me all the days of my life: and I will dwell in the house of the Lord for ever.
