Here is a little more confusion to deal with:
Amos 3:6
6 Shall a trumpet be blown in the city, and the people not be afraid? shall there be evil in a city, and the LORD hath not done it?
(KJV)
You have to understand the intent of the word evil. In the case of God sending an evil spirit to accomplish judgment on someone or to bring someone to a humble state, etc. this is the sovereign position that God has and he can use whoever for whatever to perform his ultimate will.
As for God doing evil or creating evil I will give you one more verse to make you completely confused then hopefuly I will iron this thing out.
Isa 45:7
7 I form the light, and create darkness: I make peace, and create evil: I the LORD do all these things.
(KJV)
take a look at "Barns note"
Isaiah 45:7 PP3
[And create evil] The parallelism here shows that this is not to be understood in the sense of all evil, but of that which is the opposite of peace and prosperity. That is, God directs judgments, disappointments, trials, and calamities; he has power to suffer the mad passions of people to rage, and to afflict nations with war; he presides over adverse as well as prosperous events. The passage does not prove that God is the author of moral evil, or sin, and such a sentiment is abhorrent to the general strain of the Bible, and to all just views of the character of a holy God.
(from Barnes' Notes)
A close look at the term "evil"
7451 ra` (rah);
from 7489; bad or (as noun) evil (natural or moral):
KJV-- adversity, affliction, bad, calamity, + displease (-ure), distress, evil ([-favouredness], man, thing), + exceedingly, X great, grief (-vous), harm, heavy, hurt (-ful), ill (favoured), + mark, mischief (-vous), misery, naught (-ty), noisome, + not please, sad (-ly), sore, sorrow, trouble, vex, wicked (-ly, -ness, one), worse (-st), wretchedness, wrong. [Incl. feminine ra` ah; as adjective or noun.].
We find that evil can mean simply the opposite of peace. A similar troubling term is hate:
Luke 14:26
26 If any man come to me, and hate not his father, and mother, and wife, and children, and brethren, and sisters, yea, and his own life also, he cannot be my disciple.
(KJV)
This is similar to "evil" in the way it is used. We see it is used to mean that a man must put Jesus above his family. Hate is a term here that means to give a lesser state of importance.
Have I made things clearer or messed this whole thing up. I thought I'd throw all that other stuff in here so it didn't take you by supprise.
