Well if they would have followed the bible and cast out the evil it wouldn’t be a problem.
Matthew 13:24-30
He proposed another parable to them.
“The kingdom of heaven may be likened to a man
who sowed good seed in his field.
While everyone was asleep his enemy came and sowed weeds
all through the wheat,
and then went off.
When the crop grew and bore fruit, the weeds appeared as well.
The slaves of the householder came to him and said,
‘Master, did you not sow good seed in your field?
Where have the weeds come from?’
He answered, ‘An enemy has done this.’
His slaves said to him,
‘Do you want us to go and pull them up?’
He replied,
‘No, if you pull up the weeds
you might uproot the wheat along with them.
Let them grow together until harvest;
then at harvest time I will say to the harvesters,
“First collect the weeds
and tie them in bundles for burning;
but gather the wheat into my barn.”’”
