In the beginning, the Word (Logos) already existed, and the Word was with God. The Word (Logos) was the source of Life, and the Life brought Light to people. The Light shines in the darkness. God sent His messenger, John the Baptist, to witness to people about the Light (Christ), so that they could hear the message and believe.
John was predicted to come according to Old Testament prophecy. Matthew includes a descrition of John's actvity in Chapter 3:3 of his gospel:
This is He who was spoken of through the prophet Isaiah: "A voice of one calling in the desert, prepare the way for the Lord, make straight paths for Him."
As the last of the Old Testament prophets, John was to represent another Old Testament prophet, Elijah. Malachi 3:1 says:
"See, I will send my messenger, who will prepare the way for me. Then suddenly the Lord you are seeking will come to His temple; the messenger of the covenant, whom you desire, will come,," says the Lord Almighty.
John the Baptist acted in the spirit of Elijah, and Elijah will act in his spirit duirng end times. Malachi 4:5-6 tells us:
"See, I will send you the propht Elijah before that great and dreadful day of the Lord comes. He will turn the hearts of the fathers to their children, and the hearts of the children to their fathers; or else I will come and strike the land with a curse."
When John heard, in prison, about Christ's works, he send two of his disciples to ask Him if He was the One, and Jesus answered them in Matthew 11:4-5:
Jesus replied, "Go back and report to John what you hear and see. The blind receive sight, the lame walk, those who have leprosy are cured, the deaf hear, the dead are raised, and the good news is preached to the poor."
The real Light that shines on all came into the world. The structure of John's gospel testifies to this saving truth, found only in Jesus Christ. John included a double beginning to his gospel-the prologue and John the Baptist's testimony in verse 29:
"...Behold, the Lamb of God, who takes away the sin of the world."
John also included a double ending to his gospel in chapter 20:30-31:
"Jesus did many other miraculous signs in the presence of His disciples...But these are written that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in His name."
Jesus came as the Light to the world, so that whoever follows Him will not walk in darkness (John 8:12). What should we do with this new insight into God's call on our lives? Paul tells us in 2Corinthians4:5-7:
"For we do not preach ourselves, but Jesus Christ as Lord, and ourselves as your servants for Jesus' sake. For God, who said, 'Let light shine out of darkness,' made his Light shine in our hearts to give us the light of the knowledge of the glory of God in the face of Christ. But we have this treasure in jars of clay to show that this all-surpassing power is from God and not from us."
We need to be transformed daily by the Holy Spirit, who has revealed the Light to us, as He did to John the Baptist and John the apostle. We are entrusted with keeping the Light as Christ's disciples, sharing His Good News with people around us who are perishing every day in darkness.
