In the New Testament, Lord is the most frequently used title for Jesus Christ. Although we rarely use this term in our daily lives, we are all quite familiar with another word: boss. That is basically what Lord means—one possessing authority, power, and control.
The realm of Christ's reign covers everything that happens in heaven and on the earth. No one—not even those who deny His existence—can be free of His rule or outside His sphere of authority. Although Satan tries to convince us that liberty is found in doing what we want, true freedom is acquired only through submission to Christ's loving lordship Have you submitted to Christ's rule over your life? His authority causes anger or fear in individuals who have not yet yielded to Him, but those who have experienced His lovingkindness, trusted in His goodness, and surrendered to His authority take comfort in knowing Him as the Lord of their lives.
