约翰福音第一章第17节说律法是通过摩西给的，而恩典和真理是通过耶稣基督实现的。罗马书说摩西所给的律法本是让人知罪。一旦人知罪，就会盼望弥赛亚的到来，因为旧约的先知们预言将会有弥赛亚降世把他的百姓从罪里救出来。耶稣就是预言里所说的那个弥赛亚，道成肉身来世上，死在十字架上担当了人的罪。相信耶稣的人就因信称义有永生，这是神的恩典与真理。因此说恩典和真理是通过耶稣基督实现的。
约1:17 律法本是借着摩西传的、恩典和真理、都是由耶稣基督来的。
For the law was given through Moses. Grace and truth were realized through Jesus Christ.
约1:18 从来没有人看见神．只有在父怀里的独生子将他表明出来。
No one has seen God at any time. The one and only Son, who is in the bosom of the Father, he has declared him.
罗3:20 所以凡有血气的没有一个、因行律法、能在神面前称义．因为律法本是叫人知罪。
Because by the works of the law, no flesh will be justified in his sight. For through the law comes the knowledge of sin.
