There are many who walk amongst us with disturbing, unclean spirits. These are the killers, the rapist, the evil people. The ones that have no regard at all for life. These are the people who need to be in hell but are walking the earth instead. We have to ask God for protection. We have to pray everyday for the angels to show us favor. And ask for wisdom and understanding so as not to fall prey to such things. Yes, bad things happen to good people and we have not the answer. Only God does.
Be strong in the Lord, and in the power of His might….put on the whole armor of God, that you may be able to stand against the wiles (trickery) of the devil….for we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places….wherefore take unto you the whole armor of God, that you may be able to withstand in the evil day, and having done all to stand….stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness….and your feet shod with the preparation of the gospel of peace….above all, taking the shield of faith, wherewith you shall be able to quench (put a stop to) all the fiery darts (tests, trials) of the wicked….and take the helmet of salvation, and the sword of the Spirit, which is the word of God….praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints.
