The term Lord is not one that is readily used in our world today, at least not in the west. However, it was widely used in biblical times. You will find it in the Bible mostly to reference God, but also in reference to one who is in charge, a sovereign.
God is the sovereign Lord, the ruler of heaven and earth and he is worthy of our worship!
In 1 Chronicles 16:29 we are told to, “ascribe to the Lord the glory due his name; bring an offering and come before him. Worship the Lord in splendor of his holiness.” The Lord alone is worthy of our adoration and worship.
The Psalms are filled with calls to praise the Lord including Psalm 95:6, “Come, let us bow down in worship, let us kneel before the Lord our maker.” And Jesus also tells us to worship the Lord your God and serve him only.
The term Lord brings about it thoughts of ultimate control, leadership, and authority. To call someone their Lord, one is affirming that they live in submission to them.
God being our Lord means that we yield ourselves to his will and his ways and affirm that he is in control! God being our Lord should definitely move us to worship!
