For over a year, this is what I kept asking Orthodox Christians: "What is different?" For obviously, holiness and grace are found everywhere in many different kinds of people.
So now I've been chrismated for just under 24 hrs., and what I'm experiencing reminds me of when I registered positive for pregnancy tests oh so many years ago--I would think about the test results, and then ask myself, "Well, do I feel any different?"
I think things might in fact be subtly different, but it's easy to delude oneself in various ways, and anyhow, I just want to quit thinking about it and instead, focus on God and other people, and what's at hand, and leave that question to God so as to let Him surprise me or not as He sees fit.
"The kingdom of God cometh not with observation; neither shall they say, Lo here! or, Lo there! For behold, the kingdom of God is within you. (Luke 17:20-21) "This manner of life we have within us, that is to say, we have it within us when we desire and will it. We do not need to wait a long time, or until our departure from this life; instead, faith and a God-pleasing life which accompanies faith are very near us. " Blessed Theophylact (+c. 1108)
In terms of shock and awe (in a good way, I mean), what really astounded me was how my priest drove many miles to the service despite a newly broken arm and apparently some really awful stomach kind of flu. He was there for just that part of the service, and then went home and the other priests did the rest of the service. What a shepherd!
