Next time you hear someone say "That is the work of the devil" remind them: ...I make peace and create evil; I the lord do these things. Isaiah 45:7

Christians avoid that Bible passage like the plaque for good reason. They constantly condemn the devil (aka "The Enemy") yet also state that their god is omnipotent and omnipresent. This means that he not only knew what his creation would do ahead of time, but also that could have prevented it. Definitely not the sign of an all-loving god!
