Should I or Shouldn't I?

From St. John of Kronstadt...

If you wish to correct anyone from his faults, do not think of correcting him solely by your own means: you would only do harm by your own passions, for instance by pride and by the irritability arising from it; "but cast thy burden upon the Lord," and pray to God "Who trieth the hearts and reins," with all your heart, that He Himself may enlighten the mind and heart of that man. He will infallibly fulfill the desire of your heart if your prayer breathes love.

If you're like me, the word "reins" may throw you a bit. It comes up a lot in Orthodox liturgical materials, and I've always gotten the gist of the meaning from the context. Originally it meant the "lower back and kidneys" and came to mean the seat of deep feelings. It is very similar to our use of "heart". So, "heart and reins" is similar to, "...the bottom of my heart" or some such thing. It's the place in us that knows what it knows and can often remain hidden from our consciousness.
