Introduction:
The title "Lord Jesus" is a central designation in Christian theology, reflecting both the divinity and the humanity of Jesus Christ. The term "Lord" signifies authority, sovereignty, and divinity, while "Jesus" is the personal name given to the Son of God at His incarnation. This entry explores the biblical foundation, theological significance, and the role of Lord Jesus in the life of believers.

Biblical Foundation:
The New Testament frequently refers to Jesus as "Lord," underscoring His divine authority and role as the Messiah. In the Gospel of Luke, the angel announces to the shepherds, "Today in the city of David a Savior has been born to you. He is Christ the Lord" (Luke 2:11). This proclamation highlights the fulfillment of Old Testament prophecies concerning the coming of a divine Savior.

The Apostle Paul emphasizes the lordship of Jesus in his epistles. In Romans 10:9, he writes, "If you confess with your mouth, 'Jesus is Lord,' and believe in your heart that God raised Him from the dead, you will be saved" . This verse underscores the necessity of acknowledging Jesus' lordship for salvation.

Theological Significance:
The title "Lord" as applied to Jesus is rich with theological implications. It affirms His pre-existence, as seen in John 1:1, "In the beginning was the Word, and the Word was with God, and the Word was God" . This passage identifies Jesus as the eternal Word, co-equal with God the Father.

The lordship of Jesus also signifies His authority over all creation. Colossians 1:16-17 states, "For in Him all things were created, things in heaven and on earth, visible and invisible, whether thrones or dominions or rulers or authorities. All things were created through Him and for Him. He is before all things, and in Him all things hold together" . This affirms that Jesus is not only the agent of creation but also its sustainer.

Role in Redemption:
The lordship of Jesus is central to the Christian understanding of redemption. Through His death and resurrection, Jesus conquered sin and death, offering salvation to all who believe. Philippians 2:9-11 declares, "Therefore God exalted Him to the highest place and gave Him the name above all names, that at the name of Jesus every knee should bow, in heaven and on earth and under the earth, and every tongue confess that Jesus Christ is Lord, to the glory of God the Father" . This passage highlights the universal recognition of Jesus' lordship and His exaltation by God the Father.

Lordship in the Life of Believers:
For Christians, acknowledging Jesus as Lord involves a commitment to follow His teachings and submit to His authority. Jesus Himself said, "If you love Me, you will keep My commandments" (John 14:15). This obedience is a response to His love and sacrifice, reflecting a transformed life under His lordship.

The early church recognized the importance of Jesus' lordship in communal worship and practice. Acts 2:36 records Peter's declaration, "Therefore let all Israel know with certainty that God has made this Jesus, whom you crucified, both Lord and Christ" . This acknowledgment was foundational for the identity and mission of the early Christian community.

Conclusion:
The title "Lord Jesus" encapsulates the profound truth of Jesus' identity as both God and Savior. It calls believers to a life of worship, obedience, and proclamation of His lordship to the world.
