According to Richard Rust, warfare is a scriptural metaphor for Christian action. The metaphor is found in the standard of liberty (Alma 51:20), in the prophet’s mouth being like a sharp sword (Isaiah 49:2; 1 Nephi 21:2), in the sword of justice (Alma 26:19, 60:29), and in the sword of the Lord’s Spirit (D&C 27:18). Lehi challenges his sons to “put on the armor of righteousness” (2 Nephi 1:23), just as the Lord’s people are to “take unto [them] the whole armour of God”--including the “shield of faith” and the “helmet of salvation” (Ephesians 6:13-17; D&C 27:15-18). An exemplary Christian leader, King Mosiah “warred a good warfare, walking uprightly before God” (Alma 1:1). [Richard D. Rust, Feasting on the Word, p. 215]
