According to 2 Corinthians 3:3, the heart of ___ is broken up and a heart of ___ is given.

The answer A, which refers to "stone" and "flesh," is correct because it reflects the scriptural context found in 2 Corinthians 3:3, which emphasizes the transformation that occurs in a believer's life. This passage underlines the idea of a transition from a hardened heart, metaphorically represented by stone, to a heart of flesh, symbolizing sensitivity and responsiveness to God's Spirit and His will.

The imagery of a "heart of stone" indicates a heart that is unyielding, resistant to change, and often associated with sin and disobedience. Conversely, a "heart of flesh" signifies a soft, tender heart that is open to God's love, guidance, and truth. This transformation is central to the work of the Holy Spirit, who enables believers to move from a state of disobedience to one of obedience and receptivity to God.

Understanding this passage helps convey the fundamental Christian belief in regeneration, where an individual undergoes a fundamental change in character and heart as part of their spiritual journey. The distinction between these two states of the heart encapsulates important theological themes regarding redemption and the new covenant established through Christ.
