Matthew 5:13-16 Salt And Light.
Salt was and is used for a number of reasons, here Jesus refers to how salt brings out the flavour in other food when it is applied. If it loses this ability then it is worthless (v. 13). Like light, salt is something people seek in order to make living possible. Light is also necessary to do anything, to go anywhere. If the light is hidden then it is as though it did not exist, and no one is helped by it (vv. 14-15). It is interesting to see these as examples of Psalm 34:8 – “Oh, taste and see that the LORD is good; blessed is the man who trusts in Him!” Jesus promises not just existence or survival for the life to come, but he promises that we might have a blessed abundant life. “The thief does not come except to steal, and to kill, and to destroy. I have come that they may have life, and that they may have it more abundantly” (Jn. 10:10). This is the flavour enhancing and life illuminating nature that the Lord’s people are called upon to be in the world, to the glory of the Father in heaven (v. 16).
