BlepoTheology

Visual Theology: Videos, Comics, Infographics and more to convey Truth

βλέπω (blep'-o):
to discern mentally, observe, perceive, discover, understand

Blepo suggests "to see something physical, with spiritual results (perception)." That is, it carries what is seen into the non-physical (immaterial) realm so a person can take the needed action (respond, beware, be alert).
