The beginning of the Gospel of Mark anticipates—right away—that the
narrative will climax at the Jerusalem temple. This “gospel” of Jesus Christ in
Mark 1:1 is “as it is written” (καθὼς γέγραπται; 1:2) in Isaiah. The meaning of
“gospel,” therefore, should be sought in the first place in Isaiah, specifically in
the context of Isaiah 40:3 which is what Mark quotes in 1:3.
