Christian Dialysis

Jeremiah 12:2 ....thou art near in their mouth, and far from their reins.
Throughout the Old Testament and the New Testament God stresses the essential importance of transparency.  Our outward words may sound eloquent and sincere, and may even bring about desired results.  But God looks on the heart. 
The word used in this verse is "reins."   This is literally the kidneys, but of course, represents the inward self.  It is interesting that the kidneys are used in many places in the Old Testament to refer to the inner man.  The kidneys are an essential organ, purifying the blood.  We cannot live without this purifying process.  If the kidneys cease their normal functioning, dialysis must be prescribed. 
How many Christians are living on "dialysis?"  Though they continue to speak the words of faith, their inner man is dying, ceasing to filter the toxins of the world.  They no longer allow God's Word to enter into their deepest selves, cleansing and purifying their lives from within.  Sophisticated programs and plans may prolong their lives and maintain healthy appearances, allowing normal living for long periods of time.  However, while the development of dialysis has been a tremendous blessing to millions of people, medical professionals confirm that it is not a permanent substitute for the functioning of healthy kidneys.  Similarly, there is no substitute for the filter of God's Word and the guidance of the Holy Spirit.  Eventually, our "sin will find us out" (Numbers 32:23).
Lord, show me when my words are just for show.  I want my "reins" to be controlled and sustained by You, not by outward, artificial means.
