Matthew 5:13-16 ESV
13 “You are the salt of the earth, but if salt has lost its taste, how shall its saltiness be restored? It is no longer good for anything except to be thrown out and trampled under people’s feet. 14 “You are the light of the world. A city set on a hill cannot be hidden. 15 Nor do people light a lamp and put it under a basket, but on a stand, and it gives light to all in the house. 16 In the same way, let your light shine before others, so that they may see your good works and give glory to your Father who is in heaven.
Philippians 2:14-16 ESV
14 Do all things without grumbling or disputing, 15 that you may be blameless and innocent, children of God without blemish in the midst of a crooked and twisted generation, among whom you shine as lights in the world, 16 holding fast to the word of life, so that in the day of Christ I may be proud that I did not run in vain or labor in vain.
Romans 12:2 ESV
2 Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.
Ephesians 4:29 ESV
29 Let no corrupting talk come out of your mouths, but only such as is good for building up, as fits the occasion, that it may give grace to those who hear.
Romans 13:12-14 ESV
12 The night is far gone; the day is at hand. So then let us cast off the works of darkness and put on the armor of light. 13 Let us walk properly as in the daytime, not in orgies and drunkenness, not in sexual immorality and sensuality, not in quarreling and jealousy. 14 But put on the Lord Jesus Christ, and make no provision for the flesh, to gratify its desires.
Luke 6:31 ESV
31 And as you wish that others would do to you, do so to them.
