If all things eminated from god, then he is at war with his own creation, which is...

merely an aspect of himself ergo, god is both god and the devil.

Depending on how you trigger him.

I wouldn't fuck with the guy.

They made him jealous with their foreign gods
and angered him with their detestable idols.
17 They sacrificed to false gods, which are not God—
gods they had not known,
gods that recently appeared,
gods your ancestors did not fear.
18 You deserted the Rock, who fathered you;
you forgot the God who gave you birth.

19 The Lord saw this and rejected them
because he was angered by his sons and daughters.
20 “I will hide my face from them,” he said,
“and see what their end will be;
for they are a perverse generation,
children who are unfaithful.
21 They made me jealous by what is no god
and angered me with their worthless idols.
I will make them envious by those who are not a people;
I will make them angry by a nation that has no understanding.
22 For a fire will be kindled by my wrath,
one that burns down to the realm of the dead below.
It will devour the earth and its harvests
and set afire the foundations of the mountains.

23 “I will heap calamities on them
and spend my arrows against them.
24 I will send wasting famine against them,
consuming pestilence and deadly plague;
I will send against them the fangs of wild beasts,
the venom of vipers that glide in the dust.
25 In the street the sword will make them childless;
in their homes terror will reign.
The young men and young women will perish,
the infants and those with gray hair.
26 I said I would scatter them
and erase their name from human memory,
27 but I dreaded the taunt of the enemy,
lest the adversary misunderstand
and say, ‘Our hand has triumphed;
the Lord has not done all this.’”
