Why is calling Jesus 'Lord' important for Christians?

In the context of the sermon, the act of referring to Jesus as 'Lord' is significant because it recognizes His divine authority and position over creation. The Roman centurion exemplifies this by calling Jesus 'Lord' and requesting His help, understanding that to acknowledge Jesus as Lord is to submit to His authority. Romans 10:9 emphasizes this confession, stating, 'That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved.' This underscores the importance of recognizing Jesus’ lordship in achieving both personal faith and communal worship, reflecting the believer's dedication and reverence.
