The Need For Righteousness.
Jesus Came To Fulfill The Law.
Do not think that I am come to destroy the law or the prophets: I am not come to destroy them but to fulfil. For verily I say unto you, until heaven and earth shall pass, not one jot or one tittle shall pass from the law until all be fulfilled. Matthew 5:17.
Exceeding In Righteousness.
Whosoever, therefore, shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven. For I say unto you, That except your righteousness shall exceed the righteousness of the scribes and Pharisees, you shall in no way enter into the kingdom of heaven. Matthew 5 vs 17-20.
Holy Spirit The Reprover Of Righteousness.
But now I go my way to Him that sent Me; and none of you asks Me, where are you going? But because I have said these things unto you, sorrow has filled your heart. Nevertheless, I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send Him unto you. And when He has come, He will reprove the world of sin, and of righteousness, and of judgment: Of sin, because they believe not on Me; Of righteousness, because I go to My Father, and you see Me no more; Of judgment, because the prince of this world is judged. I have yet many things to say unto you, but you cannot bear them now, however when He, the Spirit of Truth, is come, He will guide you into all truth: for He shall not speak of Himself; but whatsoever He shall hear, that shall He speak: and He will show you things to come.
He shall glorify Me: for He shall receive of mine, and shall show it unto you. All things that the Father has are Mine: therefore said I, that He shall take of Mine, and shall show it unto you. A little while and you shall not see Me: and again, a little while, and you shall see Me because I go to the Father. John 16 vs 5-16.
