Saved for Saltiness
lit. as seasoning for food or as fertilizer Mt 5:13b; Mk 9:50ab; Lk 14:34
fig., of the spiritual qualities of the disciples (cp. Diogenes 4 p. 94, 13 Malherbe, of the men at Athens) τὸ ἅ. τῆς γῆς Mt 5:13a; cp. Mk 9:50c
God intends the most powerful of all restraints within sinful society to be his own redeemed, regenerate and righteous people.
As R. V. G. Tasker puts it, the disciples are ‘to be a moral disinfectant in a world where moral standards are low, constantly changing, or non-existent’.3
Christian saltiness is Christian character as depicted in the beatitudes, committed Christian discipleship exemplified in both deed and word. For effectiveness the Christian must retain his Christlikeness, as salt must retain its saltness. If Christians become assimilated to non-Christians and contaminated by the impurities of the world, they lose their influence. The influence of Christians in and on society depends on their being distinct, not identical.
