U- Unveiling the Word

πώρωσις represents a state of spiritual hardening or insensitivity. Originally a medical term describing the formation of calluses or the healing process of bones, it developed profound theological significance in describing the condition of hearts resistant to divine truth. In New Testament usage, particularly in Mark and Paul’s writings, it describes a spiritual condition that prevents understanding and acceptance of God’s revelation. Early church fathers saw in this term both a warning about the progressive nature of spiritual resistance and hope in God’s ability to heal spiritual callousness. Today, this word continues to challenge believers to maintain spiritual sensitivity while offering hope for those experiencing spiritual hardening.
