Listen! It’s the voice of someone shouting, “Clear the way through the wilderness for the LORD! Make a straight highway through the wasteland for our God! Fill in the valleys, and level the mountains and hills. Straighten the curves, and smooth out the rough places. Then the glory of the LORD will be revealed, and all people will see it together. The LORD has spoken!” Isaiah 40:3-5 NLT
The custom was in ancient times that when a king was to travel to another part of his kingdom, the roads would be smoothed out to make the trip easier. The potholes and ruts would be filled and made smooth. The high areas were lowered in preparation of the king’s visit. Isaiah predicted that there would be a forerunner for the Messiah. John the Baptist was the person predicted. He helped prepare people’s hearts for the Messiah.
The Holy Spirit is preparing our hearts today so that we are ready when Jesus returns.
Then John went from place to place on both sides of the Jordan River, preaching that people should be baptized to show that they had repented of their sins and turned to God to be forgiven. Isaiah had spoken of John when he said, “He is a voice shouting in the wilderness, ‘Prepare the way for the LORD’s coming! Clear the road for Him! The valleys will be filled, and the mountains and hills made level. The curves will be straightened, and the rough places made smooth. And then all people will see the salvation sent from God.'” Luke 3:3-6 NLT
