Anyone who knows my husband can probably tell you right off that his favorite scripture verse is Matthew 5:16.
He is always telling people to let their light shine.
People should be able to see you and know that you are different. Your behavior, words and demeanor all should be godly, all the time.
It isn't easy to be a light in this dark world. Everyday circumstances will try to drag you down and suck you up.
Stay strong, stay bright. You will shine brighter too, if you are around other brightness. Choose your friends wisely and encourage each other to shine on.
Let your light shine before men in such a way that they may see your good works, and glorify your Father who is in heaven. (Matthew 5:16 NASB)
