What Does Mark 9:50 Mean?

Jesus concluded: 'Salt is good: but if the salt have lost his saltness, wherewith will ye season it? Have salt in yourselves, and have peace one with another' (Καλὸν τὸ ἅλας· ἐὰν δὲ τὸ ἅλας ἄναλον γένηται, ἐν τίνι αὐτὸ ἀρτύσετε; ἔχετε ἐν ἑαυτοῖς ἅλα, καὶ εἰρηνεύετε ἐν ἀλλήλοις). Salt represents distinctive Christian character—purity, preservation, seasoning. Salt that loses saltiness (becomes 'unsalted,' analon, ἄναλον) is useless, fit only to be trampled (Matthew 5:13). Disciples must maintain spiritual vitality and moral distinctiveness. 'Have salt in yourselves' means cultivate grace, holiness, and covenant faithfulness. The connection to 'have peace one with another' recalls the chapter's beginning—disciples argued about greatness (v. 34), Jesus taught humility (vv. 35-37). Salt preserves peace by purifying pride, envy, and selfish ambition. Sanctified believers live peaceably because self-interest has been 'salted'—purified through trials and self-denial.
