“It seems to me that, already, the great Moses knew about this mystery by means of the light in which God appeared to him, when he saw the bush burning without being consumed (cf. Ex 3:1ff.). For Moses said: “I wish to go up closer and observe this great vision.” I believe that the term “go up closer” does not indicate motion in space but a drawing near in time. What was prefigured at that time in the flame of the bush was openly manifested in the mystery of the Virgin, once an intermediate space of time had passed.
As on the mountain the bush burned but was not consumed, so the Virgin gave birth to the light and was not corrupted. Nor should you consider the comparison to the bush to be embarrassing, for it prefigures the God-bearing body of the Virgin.”Gregory of Nyssa , On the Birth of Christ, PG 46, 1133 D-1136 B.
As the Virgin bore the flame of divinity in her body, we are given the gift of carrying His Spirit. Moses saw this miracle almost 1500 years before the incarnation. We are given a more robust experience of having God in us; it lightens our souls and to those around us. Also, it consumes every sin, profanity and corruption in us. Did you feel the flames of the Holy Spirit in you?
