Who is God?

God is the divine presence and infinite intelligence for which we have our being, the very essence of life and the energy that forms us and all things in our reality.

As such, God knows/is all things and is infinite intelligence, infinite wisdom, infinite love and infinite power. 

If God is with and in us and is all of these things, what shall we fear?

God is made of two parts, the law of love and the divine principle which is also known as the law of cause and effect. 

So essentially, God is love and law.  If we think on that which is right, just, loving and beautiful, we shall experience those things in our lives.
