What does it mean that Jesus is the 'Lord'?

In scripture, calling Jesus 'Lord' acknowledges His sovereign authority and divinity. In Mark 4, the disciples refer to Him as 'Master,' reflecting their recognition of His lordship, especially when they plead for salvation from the storm. This title also emphasizes that He is not just a teacher but the one who has the power to save. As the Lord Jesus, He has the ultimate authority over creation—as seen in His commands to the winds and the sea. Understanding Him as Lord encourages believers to rely on His sufficiency and grace, knowing that He is in control of all that concerns their lives.
