What is God like?

been reading Louis Berkhof's Manual of Christian Doctrine (also known as Little Louis).
got some questions for him:

how is God independent, yet all things depend on him?

how is God immutable yet ever creating, ever generating, ever sustaining?

how can we know about God's incommunicable attributes?
(that is, his independence, immutability, infinity, simplicity)


it does seem that there are two categories of attributes of God: Incommunicable and Communicable. That makes sense of a quote i read last night,

What appears as imperfect in man, exists in infinite perfection in God. (Systematic Theology (also known as Big Berkhof), p84)

which must be referring not to the incommunicable but the communicable. that makes much more sense.
