God alone will be worshiped
On that day life-giving waters will flow out from Jerusalem, half toward the Dead Sea and half toward the Mediterranean, flowing continuously in both summer and winter. And the Lord will be king over all the earth. On that day there will be one Lord—his name alone will be worshiped. Zechariah 14:8-9
In the beginning there was only God and in the end there will be one Lord who “will be king over all the earth.” What prophet Zechariah was announcing was eschatological in nature. He was describing the event that will transpire in the end time. From the text, he shows a wider concept of the Lord’s blessing. There will be a never ending supply of God’s blessings. God will become visibly king over all the earth. In the meantime, God is working out His plan of reconciling people to Himself as revealed in His word. During the time of John the Baptist, people became interested when he was announcing the coming of the Kingdom of God. In his announcement, he was calling on people to repent. “Repent of your sins and turn to God, for the Kingdom of Heaven is near” (Matthew 3:2). There is one final invitation that God wants people to respond. “The Spirit and the bride say, “Come.” Let anyone who hears this say, “Come.” Let anyone who is thirsty come. Let anyone who desires drink freely from the water of life” (Revelation 22:17). The Creator would be universally recognized due to the influence of the living water which is the gospel. “On that day life-giving waters will flow out from Jerusalem” (Zechariah 14:8). Zechariah’s prophecies provided affirmation that God will deliver those who place their trust in God. One of the earliest confessions of the early church was the simple one, “Jesus is Lord” (see Romans 10:9; Acts 2:36; see also Matthew 28:18; Ephesians 1:20, 21). The grand consequence of Jesus’ status and work is for the purpose that “every knee should bow” and “every tongue confess that Jesus Christ is Lord” (Philippians 2:11). In Isaiah 45:22-23, the language of this passage is echoed: “Turn to me and be saved, all you ends of the earth; for I am God, and there is no other. By myself I have sworn, my mouth has uttered in all integrity a word that will not be revoked: Before me every knee will bow; by me every tongue will swear.” The Scripture is a completed book that contains all that we will ever need regarding salvation, Christian life, and the life to come. “These are written so that you may continue to believe[d] that Jesus is the Messiah, the Son of God, and that by believing in him you will have life by the power of his name” (John 20:31).
