Most assuredly, I say to you, unless you are born again, you cannot see the kingdom of God. John 3:3
We tend to think of our birth as a one-time event, and yet in reality it’s happening all the time. This is because the Lord is creating all the time. Creation isn’t a past event. If it were, we’d cease to exist. Our very survival depends upon His perpetual creation. Take the cells in the human body – many of these are replaced or regenerated every seven to ten years. Or think of spring. All the trees and flowers and shrubs, all living vegetation, is "born again" each year. The birth of new life is all around us which is why the Lord’s words in John 3:3 - you must be “born again” - don't have to be viewed as strange or mystical. If we were perfect beings then perhaps there’d be no need for re-birth. The hells try to convince us we don’t need to change, but this is a lie. The greatest thing we can do right now is be open to change - break out of old patterns and behaviors, and use the creative energy given to us by our Creator to try new things. That way we “give birth” to new states, new ways of thinking, new ways of doing, and new ways of living in His image.
In the state of infancy that a person passes through when being regenerated spiritual things are present in potentiality, for spiritual life emerges, as if from an egg, out of each consecutive age. The phase of infancy is so to speak the egg for that of childhood; the phase of childhood is so to speak the egg for that of adolescence and youth; and this phase is as it were the egg for that of adult years. Thus the person is so to speak repeatedly experiencing birth. Secrets of Heaven 4378.
