It's good to read the whole chapter. It lays out good parameters for God's people to walk within, maintaining good works and godly conduct so that we do not bring "bad light" to the name of Christ.
Here is a passage of scriptures that correspond to this.
Matthew 5:9-16
[9]Blessed are the peacemakers: for they shall be called the children of God.
[10]Blessed are they which are persecuted for righteousness' sake: for theirs is the kingdom of heaven.
[11]Blessed are ye, when men shall revile you, and persecute you, and shall say all manner of evil against you falsely, for my sake.
[12]Rejoice, and be exceeding glad: for great is your reward in heaven: for so persecuted they the prophets which were before you.
[13]Ye are the salt of the earth: but if the salt have lost his savour, wherewith shall it be salted? it is thenceforth good for nothing, but to be cast out, and to be trodden under foot of men.
[14]Ye are the light of the world. A city that is set on an hill cannot be hid.
[15]Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house.
[16]Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.
