"The first heaven we experience is when we realize int he depths of our heart that we live under the eye of God. The question we must ask the heart is, 'Am I comfortable under the eye of God? Or is God getting too close?' We are strange and lovely creatures. We can ache for God tremendously yet find ourselves getting nervous if God gets too close. After all, the closer God gets, the more we hear the call to be divinized [sanctified?]. It is both exciting and frightening to hear that call. Being divinized is still part of the unknown even though it is our baptismal invitation. We prefer to keep the comfortable masks that we know rather than go through the purifying process of becoming like unto God."
