What do we mean when we say that God is the Creator of heaven and earth?
When we say that God is the Creator of heaven and earth we mean that He made all things from nothing by His almighty power.
(a) Only God can create, that is, make something from nothing, because creation requires infinite power, which God alone possesses.
(b) All things except God depend on a cause for their existence and hence must have been created by God.
(c) God did not have to create the world; He did so freely.
(d) God preserves all creatures; otherwise, they would at once return to nothingness. He also governs all things, and in the divine government of the world nothing does or can happen unless God wills or permits it.
(e) Evil is the lack of some perfection. God does not will physical evil in itself but only insofar as it is connected with some good.
(f) God wills or permits the physical evils of life in order to punish sin, to make sinners repent, to try the just and make them worthy of everlasting reward, or to be the occasion of some other greater good.
(g) God permits but does not will moral evils.
