Therefore do not become partners with them; ⁸ for at one time you were darkness, but now you are light in the Lord.  Walk as children of light.
(Ephesians 5:7-8 -- ESV)

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.
(Matthew 5:15-16 -- ESV)
