Context: The Greek verb κατανύσσω is a vivid term that conveys the idea of being pierced or pricked deeply, often resulting in a profound emotional or spiritual reaction. This word is notably used in Acts 2:37, where it describes the reaction of the crowd upon hearing Peter's sermon on the day of Pentecost: "When the people heard this, they were cut to the heart and asked Peter and the other apostles, 'Brothers, what shall we do?'" (BSB). Here, κατανύσσω captures the intense conviction and realization of guilt that the listeners experienced, prompting them to seek guidance and repentance.

The use of κατανύσσω in this context highlights the power of the Holy Spirit working through the apostolic message, leading to a transformative moment for the hearers. This piercing of the heart signifies not just an emotional response but a spiritual awakening that compels action, aligning with the broader biblical theme of repentance and conversion.

In a broader theological sense, κατανύσσω can be understood as a divine intervention where the truth of God's word penetrates the human heart, leading to a recognition of sin and the need for salvation. This aligns with the biblical narrative of God actively engaging with humanity, calling individuals to repentance and a renewed relationship with Him.
