"Let your light so shine before men, that they may see your good works and give glory to your Father who is in heaven."
All them heathens giving "glory to God" eh?
Is that what you would call that which goes on here?
If you notice this is not a salvation verse , nor does it say that this will save anyone.
From Matthew Henry
The prophets, who went before them, were the salt of the land of Canaan; but the apostles were the salt ofthe whole earth, for they must go into all the world to preach the gospel. It was a discouragement to them that they were so few and soweak. What could they do in so large a province as the whole earth?Nothing, if they were to work by force of arms and dint of sword; but, being to work silent as salt, one handful of that salt would diffuse its savour far and wide; would go a great way, and work insensibly and irresistibly as leaven, ch. 13:33. The doctrine of the gospel is as salt; it is penetrating, quick, and powerful (Heb. 4:12); it reaches the heart Acts 2:37. It is cleansing, it is relishing, and preserves from putrefaction. We read of the savour of the knowledge of Christ (2 Co. 2:14); for all other learning is insipid without that. An everlasting covenant is called a covenant of salt (Num. 18:19); and the gospel is an everlasting gospel. Salt was required in all the sacrifices (Lev. 2:13), in Ezekiel’s mystical temple, Eze. 43:24. Now Christ’s disciples having themselves learned the doctrine of the gospel, and being employed to teach it to others, were as salt. Note, Christians, and especially ministers, are the salt of the earth.
The question at hand is does your behavior save anyone?
