Everyone is not "Sons of God", I hope you are, but the fact is everyone is not.
The bible tells a story of Eve being seduced by an animal controled by an evil spirit. - it's offspring still are today.
This is the man that planted evil seeds, and there was one who planted good seeds(God), but when they come up they were all together, ....tares and wheat...
The Angels said "shall we root them up now", and the master said "let them grow together untill the harvest, then bind the tares in bundles to be burned.... and gather the wheat together the garner.
This speaks of two different people "the children of the world" and the children of God"
