In the fifteenth year of the reign of Tiberius Caesar—when Pontius Pilate was governor of Judea, Herod tetrarch of Galilee, his brother Philip tetrarch of Iturea and Traconitis, and Lysanias tetrarch of Abilene—during the high-priesthood of Annas and Caiaphas, the word of God came to John son of Zechariah in the wilderness. He went into all the country around the Jordan, preaching a baptism of repentance for the forgiveness of sins. As it is written in the book of the words of Isaiah the prophet: “A voice of one calling in the wilderness, ‘Prepare the way for the Lord, make straight paths for him. Every valley shall be filled in, every mountain and hill made low. The crooked roads shall become straight, the rough ways smooth. And all people will see God’s salvation.’” - Luke 3:1-6
In many ways, we are called to do the same as John: do our best to make the path straight. John called the people to recognize their place before God and recognize their need to be ready to change. That way, when the Messiah actually shows up, they are already in the prime position to respond to his message. We are not the message. We are the hospitable house, the helping hand, the wise word, the guest at the meal--all of which makes the path straight. Really we are enlisting in the task God has already begun.
When we say "makes the path straight" what we're really saying is removing unnecessary obstacles--unnecessary difficulties--to Jesus' good news. Sometimes it is clarifying, sure. But sometimes it is just getting out of the way and making sure that the important topic remains the important topic (and a rabbit trail doesn't become the big topic). It is easy to get sidetracked onto trivial topics--one for which we have a particular fondness perhaps, but one which is not the important one. When that happens, our topic becomes the idol--truth that nonetheless takes the place of the gospel.
I need to pray to get out of the way and make the path clear all the way to Jesus.
