"Dearly beloved, avenge not yourselves, but rather give place unto wrath: for it is written, Vengeance is mine; I will repay, saith the Lord. Therefore if thine enemy hunger, feed him; if he thirst, give him drink: for in so doing thou shalt heap coals of fire on his head. Be not overcome of evil, but overcome evil with good." ~ Rom 12:19

See, Budge, you are fearful for no reason. God IS in control. If "satanists" want to come here, then let them. We'll simply feed them the Word:

"So shall My Word be that goeth forth out of My mouth: it shall not return unto Me void, but it shall accomplish that which I please, and it shall prosper in the thing whereto I sent it." ~ Isa 55:11

God bless you
"Faith is to believe what you do not see; the reward of this faith is to see what you believe. ~St. Augustine
