When Christ opens our eyes beyond the natural to the invisible, that is the beginning of the training for the incorruptible. When the eyes of our understanding are being enlightened (Eph. 1:18), we are being prepared to take something higher than what is seen. The opening of the eyes brings separation from what is seen. We cannot be separated if our eyes are not opened to greater realities. The opening of eyes is for the purpose of cleansing so that we can be made holy.
