Mark introduces John the Baptist by quoting Scripture about a messenger and a voice preparing the Lord’s way (Mark 1:2–3). The quotation explains John’s role as the one who comes ahead to prepare for the Lord’s arrival.
Mark 1:1–8 opens by announcing a “beginning” and then frames John’s public work as the start of what God had already signaled in the prophets. A messenger appears in the wilderness to prepare the Lord’s road. John baptizes people in the Jordan as they confess their sins, calling them to a changed life. These verses function as Mark’s opening setup for everything that follows in the story. The passage moves quickly from a headline-like opening (verse 1) to a supporting appeal to Israel’s Scriptures (verses 2–3), and then to John’s actions and message (verses 4–8).
Mark opens with a headline: this is “the beginning of the good news” about Jesus the Messiah, and it immediately places Jesus at the center of the story (verse 1). The next move is to say these events fit what God had already signaled “in the prophets” (verses 2–3).
A careful answer keeps the immediate passage, the book's argument, and the whole-Bible storyline together, so the question is answered in context instead of as a detached idea.
Start with Mark 1:2-3, then read the surrounding section so the answer stays connected to the passage's flow.
2As it is written in the prophets, "Behold, I send my messenger before your face, Who will prepare your way before you.
3The voice of one crying in the wilderness, `Make ready the way of the Lord, Make his paths straight.`"
