Heart

EXTERNAL vs INTERNAL 
CIRCUMCISION

INDEX:

Daniel in the Lion's Den (Daniel 6)

Heart (2588) (kardia) does not refer to the physical organ but is always used figuratively in Scripture to refer to the seat and center of human life. The heart is the center of the personality, and it controls the intellect, emotions, and will. No outward obedience is of the slightest value unless the heart turns to God.

Heart (03820) (leb - note that this discussion also includes the closely related noun lebab -03824) sometimes refers to a literal heart (Ex 28:29, 1Sa 25:37, 2Ki 9:24), but most often is used figurative to refer to what I term the "control center" of our being.

Integrity (from "integer" = the whole of anything, a whole number not a fraction - think "whole character" not a fraction of one!) speaks of the unimpaired state of one's mind and heart, of moral soundness and purity, of incorruptness, of uprightness, of honesty. Just as we would talk about a whole number, so also we can talk about a whole person who is undivided. A person of integrity is living rightly, not divided, nor being a different person in different circumstances. A person of integrity is the same person in private that he or she is in public.

LORD, GIVE US UNDIVIDED HEARTS
(Psalm 86:11)

Integrity is derived from "integer" (a whole number as opposed to a fraction) and speaks of the quality of being undivided. O, to be men and women of integrity, lights shining in the midst of the darkness in such a way that the world might see our undivided hearts and this would bring glory to our Father Who is in heaven. (Mt 5:16+, cf Php 2:15+).

A great prayer to pray (daily) would be David's words...
