As you are a part of each life form on the planet, so you are a part of all existence in your universe. It is you. We are you. Sometimes you allow yourself to flow with life and at other times you do not, so your divine consciousness must be in control to allow the interaction with the angels. Your ego system, or the analytical mind, has no data input prior to an experience with an angel to believe in the interaction.
All possibilities allow the manifestation of angelic power.
This choice may or may not be conscious at that moment. No matter what your belief system your divinity can emerge just as your adrenaline can flow under certain stress conditions. An example of this is when someone can physically lift an automobile in a time of crisis. Their adrenaline rush allows them to do the seemingly impossible task. Your divine nature can express itself just like your adrenaline in a crisis.
