How do we know that there is one Lord?

The affirmation of one Lord is supported by several biblical texts, including Colossians 1:16 and Acts 2:36. Jesus is the Lord of all creation, as 'by Him all things were created,' making Him the sovereign ruler by right. Additionally, God's declaration in Acts 2, stating that Jesus is both Lord and Christ, reinforces this belief. Believers understand His lordship not just in a positional sense, but also in terms of His authority over every aspect of their lives. The acknowledgment of one Lord is foundational for unity in the faith, as it aligns all believers under His sovereign rule.
