Abinadi embellishes on the passage by Isaiah. He explains that all those who have published peace will be blessed for their efforts. This applies to those thousands of saints who were yet to proclaim the gospel. This scripture applies to the prophets and apostles of our day. How beautiful upon the Rocky Mountains are the feet of those great men whose lives have been dedicated to bringing good tidings and publishing peace! They continue to proclaim the same message that Abinadi did, that salvation comes through the sacrifice of the Only-Begotten, to break the bands of death and satisfy the demands of justice. When we raise our arm to the square to sustain the leaders of the Church, the words of Abinadi and Isaiah should come to mind, how beautiful upon the mountains are the feet of those who shall hereafter publish peace!
Mark E. Petersen
"Have you ever asked yourselves who these people are, who preach the gospel of peace and whose feet are so beautiful upon the mountains? Abinadi, in the Book of Mormon, gives us the explanation. These people are the prophets of God - they who preach the gospel of the Prince of Peace, the Lord Jesus Christ." [Quoting Mosiah 15:13-18]
"So spoke Abinadi. The prophets, then are the servants of Jesus Christ and have been from the beginning of time. . . .We honor them. We shall follow them, and through them we shall work out our salvation here on earth in the Lord's own way." (LDS Church News, Deseret News, Mar 30, 1996)
