Dr. Gil Stieglitz says, "Yes, there are some people who see angels and demons. God has given them a gift to perceive the spiritual realms and what is happening there. At first Christians who begin to perceive angels and demons can be overwhelmed by what t hey "see." God has signed them up for an adventure that many of them did not want. God wants them to grow in their faith and help others win against the schemes of Satan. This book is wonderful and mind-bending all at the same time."Angels are naturally invisible to human eyes because they are spirit, not flesh. God has given some believers the supernatural ability to "see" angels, both good and evil, in order to help Christians cooperate with or resist against what they are trying to do. As our world plunges into a time of spiritual darkness in these last days, God seems to be giving more people the ability to "see" or discern the presence and work of spirits; that is, the gift of discerning of spirits.
