That Jesus Christ is ‘LORD’, to the glory of God the Father (Philippians 2.11)
To ascribe to Jesus the title, ‘LORD’, is to assign to Him the accolade given to the God of Israel. Here is the recognition that in Jesus all that God is and proves Himself to be is met with. It is a declaration of worship.
But more than that. Here we have a vital connection with the first part of the hymn. His complete humanity was so emphasised, in v 7 and v 8. For we are called to celebrate Jesus by embracing His humanity become our humanity, His attitude and ministry expressed through our attitude and ministry.
To admit Jesus is LORD is to approach the place of harmony and submission to Him and His call. To become His disciples. It is giving ourselves to be drawn into the reality of the God who loves and invests us as a Father, who treats us and commands us as siblings of His Son, who energises and empowers us for this new identity by His Spirit.
May this bring you joy this Advent Season.
