Russ,
The distinction is the source of the power. It is possible that the snake came from outside your body, but it is still a spirit from this world, this spirit dies with this world, don't yoke yourself to it.
The fire at Pentecost came from heaven, not the earth. The day will come where you will see more impressive things than this done on earth, but they will not all come from heaven.
Abandon the Kundalini so that you are not deceived by the spirits that seek to bind you to this world.
The spirit in Christ's shed blood is the only spirit that has power over the death of this world. Go back to the cross, not the snake.
Indeed, Beware.
Nathan
