Matthew
Matthew 5:16ESV·traditional attribution

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.

John Calvin Reformed @genevareformer

16. Let your light shine before men After having taught the apostles that, in consequence of the rank in which they are placed, both their vices and their virtues are better known for a good or bad example, he now enjoins them so to regulate their life, as to excite all to glorify God.

Matthew Henry Presbyterian @wholebiblehenry

Christ had lately called his disciples, and told them that they should be fishers of men; here he tells them further what he designed them to be - the salt of the earth, and lights of the world, that they might be indeed what it was expected they should be. I. Ye are the salt of the earth.

Commenting on Matthew 5:13-16

John Gill Reformed Baptist @doctorgill

Let your light so shine before men,.... Here Christ applies the foregoing simile to his disciples, and more fully opens the meaning and design of it. His sense is this; that the light of the Gospel, which he had communicated to them, the spiritual knowledge of the mysteries of grace, which he had favoured them with, were to be openly declared, and made manifest before men.
