One of the most significant factors influencing Christians today in their devotion to Jesus, of course, is the Scriptures themselves. As we have seen, the OT uses the term “Lord” or “LORD” in reference to the God of Israel; then in the NT, “Lord” can refer to God the Father, Jesus, or occasionally the Holy Spirit. By bringing the two Testaments together, under one cover, it is an easy step for followers today to link the title “Lord” together for multiple figures. David Capes
