Matthew 5:20

For I say unto you, That except your righteousness shall exceed the righteousness of the scribes and Pharisees--The superiority to the Pharisaic righteousness here required is plainly in kind, not degree; for all Scripture teaches that entrance into God's kingdom, whether in its present or future stage, depends, not on the degree of our excellence in anything, but solely on our having the character itself which God demands. Our righteousness, then--if it is to contrast with the outward and formal righteousness of the scribes and Pharisees--must be inward, vital, spiritual. Some, indeed, of the scribes and Pharisees themselves might have the very righteousness here demanded; but our Lord is speaking, not of persons, but of the system they represented and taught. ye shall in no case enter into the kingdom of heaven--If this refer, as in Mat 5:19, rather to the earthly stage of this kingdom, the meaning is that without a righteousness exceeding that of the Pharisees, we cannot be members of it at all, save in name. This was no new doctrine (Rom 2:28-29; Rom 9:6; Phi 3:3). But our Lord's teaching here stretches beyond the present scene, to that everlasting stage of the kingdom, where without "purity of heart" none "shall see God." The Spirituality of the True Righteousness in Contrast with That of the Scribes and Pharisees, Illustrated from the Sixth Commandment. (Mat 5:21-26).

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. The circumstances of the sermon being accounted for (Mat 5:1, Mat 5:2), the sermon itself follows, the scope of which is, not to fill our heads with notions, but to guide and regulate our practice. I. He proposes blessedness as the end, and gives us the character of those who are entitled to blessedness (very different from the sentiments of a vain world), in eight beatitudes, which may justly be called paradoxes (Mat 5:3-12). 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…

5:20 unless your righteousness is better: Jesus’ disciples must have the substantially new kind of righteousness that Jesus teaches and makes possible (illustrated in 5:21-47 and summed up in 5:48); it is both quantitatively and qualitatively distinct. Just as Jesus is greater than the Temple (12:6) and Jonah (12:41), so the righteousness of his followers far outstrips that of the teachers of religious law and the Pharisees (see 3:7-9).
