The messenger before his face
Pattern
Malachi closes the Old Testament with a messenger sent to prepare the way and Elijah promised before the great day. The Gospels open exactly there: Gabriel says John will go in the spirit and power of Elias, Mark begins his book with Malachi's verse, and Jesus says of John, this is he of whom it is written.
The seam between the Testaments is a single promise kept. Four centuries of silence end with the very figure the last prophet named, and Jesus himself supplies the identification.
Behold, I will send my messenger
Elijah before the great and dreadful day
The Old Testament's last promise: Elijah sent to turn the heart of the fathers to the children.
Jesus names John as the messenger
For this is he, of whom it is written.
Mark 1:2 you are here
Mark opens his Gospel with the verse
In the spirit and power of Elias
Before John's birth the angel binds Malachi's two promises to him.
