God has three parts. Each part is God by itself and all parts together is God. All three are the entire Godhead/Trinity ruling power. Think of H20/water when thinking of God.Solid=WaterLiquid= WaterGas=WaterSolid+Liquid+Gas=WaterFather=GodSon=GodHoly Spirit=GodFather+Son+Spirit=God

Use the scripture to see if you're on the right path and trusting the right source. Many doctrines/religions are out there. Make sure you follow the one God gave.
