“Now when he was asked by the Pharisees when the kingdom of God would come, he answered them and said, ‘The kingdom of God does not come with observation (μετὰ παρατηρήσεως); nor will they say, ‘See here!’ or ‘See there!’ For indeed, the kingdom of God is within you.” (Lk 17: 20-21)
It’s not by empirical observation, which is the “scientific” method of learning something new, that the Kingdom of God “comes” into my life. The “newness” of the Kingdom of God is something I am given to experience not primarily by the physical senses of sight, hearing, taste, smell, and touch, – but in the small victories on the battleground “within me.” It is from within the invisible reality of my life, of my invisible interaction with “this age” (cf. Eph 6: 12), that the grace of God invisibly transfigures my attitude toward it all.
So let me be mindful of my heart today, and open it up to God’s grace. The great thing about grace is, I need not (and cannot) “figure it out” or “master” it, as one must the natural sciences, to progress in them. I open up to God’s grace, which comes from outside me, – from Him and not from me, – and He does the rest, coming and establishing Himself as King, within me. “O Heavenly King, the Comforter, the Spirit of Truth, Who are everywhere and fills all things; Treasury of Blessings, and Giver of Life - come and abide in us, and cleanse us from every impurity, and save our souls, O Good One.”
