"The voice of one crying in the wilderness: Prepare the way of the Lord; make His paths straight."
Mark 1:2-3 (NKJV)
The dictionary defines the word "herald" as "a royal or official messenger; a person who precedes or comes before". In medieval times heralds did everything from carrying and proclaiming messages to directing tournaments and announcing the participants for each joust. What the herald did was necessary, but it was not something they did for their own direct benefit. Heralds were people who helped to bring other people's messages and they helped others in tournaments. The herald was vital in preparing things for other people, and without them some things would not have been ready as they should have been.
John the Baptist is a biblical example of someone who was a herald. He did and said things that were necessary to help prepare people for the arrival and ministry of Jesus. John told people that someone mightier than him was coming and John baptized people in water, but he spoke of how Jesus would come and baptize people with the Holy Spirit (Mark 1:7-8). John also knew that what he was doing was not for his own benefit and he was simply preparing the way of the Lord (Mark 1:2-3); John's message was all about helping to get people ready for the work that Jesus was coming to do.
Christians today are in a similar position to John the Baptist, we are all doing a work and speaking a message that is to help prepare the way of the Lord. We can ask ourselves, what are we doing to help people be ready for the work that Jesus wants to do in their life? What message are we sharing with others through our words and actions that help to prepare the way for what God wants to do in the earth today? Every believer has a part in preparing the way of the Lord. What we do is not something we do for our own benefit, but what we do is a necessary part of the work that God wants to do in the earth today.
