What does the Bible say about Elijah's role in preparing for Christ?

The Bible speaks of Elijah's role as a forerunner of Christ, indicating the importance of preparation for receiving the Savior. In Matthew 17:10-12, Jesus confirms that Elijah has already come, referring to John the Baptist who came in the spirit of Elijah. This reflects the prophecy in Malachi 4:5-6, which declares that God will send Elijah to prepare the hearts of the people. The coming of Elijah symbolizes the message of repentance and faith that is necessary for recognizing and accepting Christ when He comes. Just as John preached repentance, God's preachers today carry forth that same message, preparing hearts to meet the Lord.
