We are all familiar with this song. There are all sorts of fun ledgends and stories as to the true meaning of this song.
There is no greater example of their unity found then when we study the birth of our precious Lord and Savior, Jesus Christ. The Old, foretells of a righteous King ( Jeremiah 23:5-6 ) that would shoot up from the stump of Jesse (Isaiah 11:1-5) , bind up the brokenhearted and proclaim freedom to the captives (Isaiah 61:1-2) and would rule over His kingdom as the Wonderful Counselor, Mighty God, Everlasting Father, and Prince of Peace (Isaiah 9:6-7). The New breathes life into the foretold King. First as a babe; born of a virgin, placed in a trough. Later as a man crucified for the sins of the many. Finally as the risen Savior who sits as King at the right hand of God (Hebrews 1:3).
The Old gives way to the New.
Together, they give us the greatest story ever told.
Together, they mold and shape the story of Christ.
As we focus on the beauty of Christ during this season, let us not forget the greatly laid out foundation given in the Old Testament. For without the beginning, there would be no ending.
