Understanding the Human Heart's Deepest Longings in Scripture
The biblical understanding of the human heart encompasses the totality of a person's inner life, serving as the center of emotions, thoughts, will, and faith [5, 12]. It is not merely an organ but the core of one's being, from which the "issues of life" flow [4, 5].
Scripture frequently describes the heart as the seat of profound longings and spiritual activity. Psalm 84:2 expresses a deep yearning for God's presence: "My soul longs, and even faints for the courts of Yahweh. My heart and my flesh cry out for the living God" [3]. These longings can manifest as desires for God's kingdom, for justice, or for the destruction of evil, and even unspoken prayers of the heart are known to God [10]. Those with understanding in their hearts are said to seek knowledge, desiring a deeper acquaintance with divine and spiritual truths [11].
The Bible emphasizes that God alone possesses complete knowledge of the human heart. Psalm 44:21 states, "won’t God search this out? For he knows the secrets of the heart" [1]. Similarly, Jeremiah 17:10 declares, "I the Lord search the heart... and know the thoughts of it" [6]. This divine insight extends to all intentions, purposes, and even the hidden wickedness within [6]. The psalmist, acknowledging this divine prerogative, prays, "Search me, God, and know my heart. Try me, and know my thoughts" [2]. God's ability to "discover deep things out of darkness" includes the profound thoughts of His own heart, which He reveals to humanity [7].
Because the heart is the wellspring of personal life, a person's character is often defined by it. Individuals are described as wise, pure, upright, righteous, pious, or good based on the state of their heart [5]. However, the heart can also be deceitful [6]. Therefore, biblical calls to repentance often involve a transformation of the heart, moving beyond mere external demonstrations to an inward change of orientation, priorities, and attitudes [8]. Joel 2:13 exhorts, "tear your hearts and not your garments," emphasizing genuine internal repentance [8].
The need for a transformed heart is a recurring theme. Ezekiel 36:26 promises, "A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh" [4]. This "new heart" signifies a change in affections and passions, while a "new spirit" implies renewed understanding, judgment, and will [13]. This transformation replaces a heart that is "hard, impenetrable, and cold" with one capable of responding to God [13]. The New Testament further highlights the heart's role in spiritual discernment, noting that Israel's true allegiance—whether for or against God—would be revealed through their response to Jesus, piercing Mary's soul with pain at His rejection [9].

- Easton's Bible Dictionary “Easton's Bible Dictionary: Heart — According to the Bible, the heart is the centre not only of spiritual activity, but of all the operations of human life. "Heart" and "soul" are often used interchangeably (Deut. 6:5; 26:16; comp. Matt. 22:37; Mark 12:30, 33), but this is not generally the case. The heart is the "home of the personal life," and hence a man is designated, according to his heart, wise (1 Kings 3:12, etc.), pure (Ps. 24:4; Matt. 5:8, etc.), upright and righteous (Gen. 20:5, 6; Ps. 11:2; 78:72), pious and good (Luke 8:15), etc. In these and such passages the word "soul" could not ”
