A study by the Barna organization recently found American Christians hold diverse and inconsistent views about the existence of spiritual beings. Three quarters of those surveyed agreed that God is the all-powerful Creator who rules the universe, but a majority of the people surveyed did not believe Satan or the Holy Spirit were real. When asked if Satan was a symbolic figure representing evil, 60 percent of the respondents agreed. 6 out of 10 people surveyed said they believe the Holy Spirit is a symbol of God’s presence and power, but not a living being.
Author of the study, George Barna says, “It’s hard for achievement-driven, self reliant, independent people to believe their lives can be impacted by unseen forces. At the same time, through sheer force of repetition, many Americans intellectually accept some ideas - such as the fact that you either side with God or Satan, there’s no in-between – that do not get translated into practice.”

Ephesians 6:11-13 GNB Put on all the armor that God gives you, so that you will be able to stand up against the Devil's evil tricks. For we are not fighting against human beings but against the wicked spiritual forces in the heavenly world, the rulers, authorities, and cosmic powers of this dark age. So put on God's armor now! Then when the evil day comes, you will be able to resist the enemy's attacks; and after fighting to the end, you will still hold your ground.
