"the heart" (Eng., "cardiac," etc.), the chief organ of physical life ("for the life of the flesh is in the blood," Leviticus 17:11 ), occupies the most important place in the human system. By an easy transition the word came to stand for man's entire mental and moral activity, both the rational and the emotional elements. In other words, the heart is used figuratively for the hidden springs of the personal life. "The Bible describes human depravity as in the 'heart', because sin is a principle which has its seat in the center of man's inward life, and then 'defiles' the whole circuit of his action, Matthew 15:19,20 . On the other hand, Scripture regards the heart as the sphere of Divine influence, Romans 2:15; Acts 15:9 . ... The heart, as lying deep within, contains 'the hidden man,' 1—Peter 3:4 , the real man. It represents the true character but conceals it" (J. Laidlaw, in Hastings' Bible Dic.).
