22大卫求神垂听他，恩待他，帮助他。他也感谢神，将他的哀哭变为跳舞；将他的麻衣解下，给他束上喜乐，好叫他的荣耀（灵）歌颂神，并不住声，赞美神，直到永远。（10～12。）我盼望藉著读这些诗，我们能看见，在旧约的经纶与神新约的经纶，是无法相比的。旧约是基于律法。诗人非常虔诚。他们爱律法，高举律法，宝贝遵守律法到极点。许多篇诗都是基于遵守律法的原则。其组成的基本因素和结构就是遵守律法。但在耶利米三十一章，神告诉祂堕落、败落的选民以色列人，祂要另立一个约，就是新约，不是基于字句的律法，乃是基于神要写在他们里面活的律法。（31～34。）今天我们正在享受这新约。活的律法，生命的律，写到新约信徒里面，就是神分赐到他们里面。因此，他们里面的神乃是生命的律。在新约里，我们这些从前死了的人已被点活，从死人中复活，重生成为新人。我们重生以后，神继续更新我们，圣别我们，变化我们，模成我们，至终在基督再来时荣化我们。
22David asked God to hear him and be gracious to him to be his help. He also thanked God for turning his mourning into dancing and loosening his sackcloth to gird him with rejoicing, that his glory (spirit) might sing psalms to God without silence and praise God forever (vv. 10-12). I hope that by reading these psalms we can see that there is no comparison between the Old Testament economy and God’s New Testament economy. The Old Testament is the old covenant, and the old covenant was based upon the law. The psalmists were very pious. They loved the law, uplifted the law, and treasured the keeping of the law to the uttermost. Many of the psalms were based upon the principle of keeping the law. The keeping of the law was the basic factor and structure of their composition. But in Jeremiah 31 God told His fallen, degraded elect, the children of Israel, that He would make another covenant, a new covenant, which would not be based upon the law of letters, but upon a living law which God would write into their being (vv. 31-34). We are enjoying this new covenant today. The living law, the law of life, being written into the New Testament believers is to have God imparted into them. Thus, God in them is the law of life. In the new covenant, we who were once dead have been enlivened, resurrected from the dead, and regenerated to become a new person. After our regeneration, God continues to renew us, to sanctify us, to transform us, to conform us, and eventually to glorify us at the second coming of Christ
