Matthäus 5:16

Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven--As nobody lights a lamp only to cover it up, but places it so conspicuously as to give light to all who need light, so Christians, being the light of the world, instead of hiding their light, are so to hold it forth before men that they may see what a life the disciples of Christ lead, and seeing this, may glorify their Father for so redeeming, transforming, and ennobling earth's sinful children, and opening to themselves the way to like redemption and transformation.

This chapter, and the two that follow it, are a sermon; a famous sermon; the sermon upon the mount. It is the longest and fullest continued discourse of our Saviour that we have upon record in all the gospels. It is a practical discourse; there is not much of the credenda of Christianity in it - the things to be believed, but it is wholly taken up with the agenda - the things to be done; these Christ began with in his preaching; for if any man will do his will, he shall know of the doctrine, whether it be of God.

II. He prescribes duty as the way, and gives us standing rules of that duty. He directs his disciples, 1. To understand what they are - the salt of the earth, and the lights of the world (Mat 5:13-16). 2. To understand what they have to do - they are to be governed by the moral law. Here is, (1.) A general ratification of the law, and a recommendation of it to us, as our rule (Mat 5:17-20). (2.) A particular rectification of divers mistakes; or, rather, a reformation of divers wilful, gross corruptions, which the scribes and Pharisees had introduced in their exposition of the law; and an authentic explication of divers branches which most needed to be explained and vindicated (Mat 5:20). Particularly, here is an explication, [1.] Of the sixth commandment, which forbids murder (Mat 5:21-26). [2.] Of the seventh commandment, against adulter…

5:16 praise your heavenly Father: Religious hypocrites seek praise for themselves; Jesus’ disciples should seek praise for God (see 1 Pet 2:12).
