Mat 5:16 Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.
In this manner, it must shine, the light of yours, in front of people so that they might see the valuable works of yours and they might recognize the Father of yours, the one in the skies.
The first Greek word in this verse is translated as "so," but it means "in this manner." It begins the verse because it refers to the previous verse, Mat 5:15. This verse talks about why we shouldn't hide "the light."
The next word is the verb translated as "shine." It is in the third person, so "it shines," but it is a command. In English, commands, "shine!" are always addressed in the second person, that is, addressed to the listener. However, using "it must shine" comes close to the sense in English. Most Greek translation, however, adds a second person "Let" to the beginning to create the sense of a command, "Let your light shine!"
Of course, the key word here is the Greek word that means "light". However, Christ using light as a metaphor for knowledge and the ability to see and understand.
The word translated as "before," is an unusual word for Christ to use. It is in adverb. The Greek words that are commonly translated as "before," are more common conjunctions. The difference is that this word as an adverb modifies the verb "shine." It has the sense of shining the light in front of people in a way that leads them forward.
The word translated as "men" is the common word for men, but it is in the possessive form, "of men." This works in English too, if we translated the previous word as "in front." This word wasn't used to refer just to men, but to "people" generally.
The verb "see" is the most common form of the word. It is in the form that indicates something "might" happen.
The words translated as "good work" don't quite carry the sense of charity that "good works" carries in English. The word translated as "good" means "beautiful", "excellent," and "praiseworthy." It doesn't mean charitable or kind. The word for "work" means "business", "productivity," or "accomplishments." It doesn't mean any action but an act that requires effort or work. It is in these great accomplishments (not simple acts of kindness) that we give to God.
The word translated as "glorify" here doesn't exactly mean "glorify" or "praise." It primarily means to think, imagine, or suppose. The word "recognize" carries both the idea of seeing someone in the mind and honoring them that the Greek word does. More about this word in this article
The "which" here is an article usually translated as "the," but without an associated noun, it takes on the sense of "the one."
The word translated as "heaven" means sky, the climate, and the universe. It is plural here, which is often the case when Christ uses it. It also meant the home of the gods in a physical sense: the sun, moon, and planets were named for the gods. More about the word in this article.
this is the first time Christ uses the word translated as "glorify," doxazo, to serve two purposes 1) recognizing or seeing God in others and 2) giving praise to God.
The Spoken Version:
“Instead,” he continued, lifting his arms, raising the imaginary lamp up high, reaching up as far has he could. He rose slowly on his tip-toes, teetering precariously as he reached out.
As he teetered on his toes, the crowd began tittering.
“On a lamp stand!” He announced triumphantly, placing his lamp. “And it lights up everyone in the house! In this way,” he continued, pointing up to his pretend lamp, “let that light of yours shine out in front of other people.”
As he said this, or perhaps right before, the sun came out from behind a cloud and blazed down so brightly that the speaker had to shield his eyes from the glare.
“So that they might see,” he said, squinting but smiling, “your worthy deeds! And, recognize your Father, the one—in the skies!”
