Note, I am not saying that god must be the source of morality, only that there is no dilemma in claiming that to be the case.
Beside the things about morality that others have already pointed out, I want to also point out an underlying implication of this claim. Since you are claiming that what seems to us to be objectively good is god's nature (that god is good in nature), you are basically putting god in a box in which anything outside the box is beyond god's reach.
For example, I think we can all agree that raping a child is wrong, correct? If god is all good, then god must think that raping a child is wrong. The question is can god decide tomorrow that raping a child is morally right? According to you, god can't decide to change. This suggests that god has no free will and is far from omnipotent.
We are BOG. Resistance is voltage over current.

Occasionally, owing to the deficiency of the English language, I have used he/him/his meaning he or she/him or her/his or her in order to avoid awkwardness of style.
He, him, and his are not intended as exclusively masculine pronouns. They may refer to either sex or to both sexes!
