Observation: Among the servant songs of Isaiah we hear the mission statement of God's chosen servant(s). "And you will be a light to guide the nations. You will open the eyes of the blind.
You will free the captives from prison, releasing those who sit in dark dungeons."
You is plural. Isaiah is prophesying to the people of God. Jesus later embodies this as God's only Son.
Application: Mission remains the same. We are called to be a light to guide the nations. The imitation of Christ in our lives brings hope for those who are hopeless, light to those who live in darkness. The preparation for advent brings us for the fulfillment of this mission; both in the christ child's birth and also in Christ's return.
Looking around the world it appears to need a bit of light.
Prayer: Lord, burn the light of Christ in my heart so that I reflect the mission you poured upon your servant.
