Most everyone, believer and non-believer alike, has heard of John the Baptist. He is one of the most significant and well-known figures in the Bible. While John was known as "the Baptist," he was in fact the first prophet called by God since Malachi some 400 years earlier. John's coming was foretold over 700 years previously by another prophet: "A voice of one calling: 'In the desert prepare the way for the LORD; make straight in the wilderness a highway for our God. Every valley shall be raised up, every mountain and hill made low; the rough ground shall become level, the rugged places a plain. And the glory of the LORD will be revealed, and all mankind together will see it. For the mouth of the LORD has spoken'" (Isaiah 40:3–5). This passage illustrates God's master plan in action as God selected John to be His special ambassador to proclaim His own coming.
