Protestant reformer Martin Luther stood before the greatest powers of his day to defend the gospel of salvation by grace through faith alone. His opponents used intimidation and threats in their attempt to persuade Luther to back down. "Of whom shall I be afraid?" Luther responded. "One with God is a majority." Zechariah’s second vision had to do with horns (v. 18). These were not musical instruments but animal horns, like those of a bull. Horns sometimes appear in Scripture as a symbol of power. They can represent nations or those who rule. Horns were also a common feature in ancient architecture and design. The sacrificial altar in Jerusalem had horns (Ex. 29:12; 1 Kings 1:51). The prophet also saw four craftsmen (v. 20). The Hebrew term can refer to many kinds of work. It could be used to speak of someone who works with metal, stone, or wood. The craftsmen were God’s agents employed by Him to defeat the powers. The number four in each case is probably not specific. It seems unlikely this prophecy was referring to four particular leaders or four specific servants of God who would oppose them, instead, it is a general promise of ultimate victory. This vision not only promises that God will be victorious in the end but also reminds us that God works through His servants. In the New Testament, those who serve God are also called “workers” (Rom. 16:3; 1 Cor. 3:9; 2 Cor. 6:1; Phil. 4:3). God often exercises His power through human agents. You may feel insignificant. However, if you belong to Jesus Christ, you are God’s agent
