Isaiah prophesied of Christ, "He will magnify the law, and make it honorable." Isaiah 42:21. To magnify is to make larger, to raise to a higher position. Christ magnified the law by showing in every part its wonderful meaning. He showed that it is to be obeyed, not only in the actions, which are seen by men, but in the thoughts, which are known only to God. To those who claimed that He came to set aside the law, 71 He said, "Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil." Matthew 5:17. To fulfill means to keep, or perform. (James 2:8.) So when He came to be baptized by John the Baptist, He said, "Thus it becometh us to fulfil all righteousness." Matthew 3:15. To fulfill the law is to obey it perfectly.

Jesus sagde til dem, der påstod, at han tilsidesatte loven: "Tro ikke, at jeg er kommen for at nedbryde loven eller profeterne; jeg er ikke kommen for at nedbryde, men for at fuldkomme". Matt.5,17. At "fuldkomme" vil sige at holde, at opfylde. (Jak. 2,8). Da han kom for at blive døbt af Johannes, sagde han: "Således bør vi opfylde alt, hvad ret er". Matt. 3,15. At opfylde loven vil sige at adlyde den fuldkomment.
