The Apostle Paul quoted Isaiah 52:7 in the tenth chapter of his epistle to the Romans. He wrote: “How then shall they call on Him in whom they have not believed? And how shall they believe in Him of whom they have not heard? And how shall they hear without a preacher? And how shall they preach unless they are sent? As it is written: ‘How beautiful are the feet of those who preach the gospel of peace, who bring glad tidings of good things!’” (10:14-15, NKJV). In Isaiah’s day, as well as Paul’s day, the most common form of transportation was walking and Isaiah said the feet that carried the gospel of peace were beautiful!
