Why is it important for Christians to acknowledge Jesus as Lord?

In 1 Corinthians 12:3, it is clearly stated that no one can truly say Jesus is Lord except by the Holy Spirit. This declaration encompasses not just verbal acknowledgment but a recognition of His sovereign authority and the transformative work of the Spirit in the believer's heart. For Christians, recognizing Jesus as Lord impacts their entire life and assurance of salvation, indicating their reliance on God's grace. It confirms their changed nature from worshiping idols to serving the living God, highlighting the work of the Holy Spirit in bringing salvation and understanding.
