How can we say Jesus is Lord by the Holy Spirit?

The assertion in 1 Corinthians 12:3 that one cannot utter 'Jesus is Lord' without the Holy Spirit emphasizes the necessity of spiritual regeneration. This implies that human nature, marred by sin from the fall of Adam, is incapable of recognizing the lordship of Christ without the illuminating work of the Holy Spirit. It underscores the totally depraved state of humanity that necessitates divine intervention for understanding and faith. Thus, true acknowledgment of Christ’s lordship is a gracious act of God rather than a mere human declaration.
