Is That Enough Salt?
Salt and Discipleship
Several New Testament passages connect salt with discipleship, including:
• Jesus calls His disciples to be the “salt of the earth,” perhaps referring to salt’s preserving or flavoring properties (Matt 5:13; Mark 9:49–50; Luke 14:34–35).
• Jesus calls His disciples to have salt within themselves and to live at peace, perhaps referring to God’s word and the effect it was to have on their lives (Mark 9:50; compare Heb 4:12, Strack and Billerbeck, Kommentar, 2:23).
• Paul admonishes the Colossians to season their speech with salt (Col 4:6).
Darlington argues that the association of salt with the people of God reminds them that their discipleship and its effect on the world carries with it a strong covenantal context (Darlington, “The Salt of the Earth,” 731). It also serves as a reminder of the final judgment, when “everyone will be salted with fire” (Mark 9:49 ESV).
