耶利米書 31:33 那些日子以後，我與以色列家所立的約是這樣：我要將我的律法放在他們裏面，寫在他們心上。我要作他們的 神，他們要作我的子民。這是耶和華說的。 34 他們各人不再教導自己的鄰舍和弟兄說：『你該認識耶和華』，因為他們從最小的到最大的都必認識我。我要赦免他們的罪孽，不再記得他們的罪惡。這是耶和華說的。」
Jeremiah 31:33 For this is the covenant that I will make with the house of Israel after those days, declares the Lord: I will put my law within them, and I will write it on their hearts. And I will be their God, and they shall be my people. 34 And no longer shall each one teach his neighbor and each his brother, saying, ‘Know the Lord,’ for they shall all know me, from the least of them to the greatest, declares the Lord. For I will forgive their iniquity, and I will remember their sin no more.”
上帝為以色列人在石板上寫下了舊約（十誡），但是當談到新約時，上帝說“我要將我的律法放在他們裏面，寫在他們心上”。 有什麼不同呢！ 外部的律法不能改變人心； 他們充其量只能解決或改變行為。 關於人類根本的問題的是罪，但罪無法通過外部的律法來解決。 律法的作用是引導我們到那位能解決我們罪的救世主，為我們的罪犧牲。 上帝要改變比我們的行為更深入； 祂要改變我們的心。 當我們成為新約的一部分時，我們不僅在思想上認識上帝，而且更重要的是我們與上帝建立了親密的關係。 上帝希望將祂的律法寫在我們的心上。 問題是，我們願意祂這樣做嗎？
God wrote the Old Covenant (the Ten Commandments) on tablets of stone for the Israelites, but when it came to the New Covenant, God said “I will write it on their hearts.” What a difference! External laws cannot change hearts; they can at best only address or alter behavior. The dilemma regarding the human problem of sin is that sin cannot be solved by external laws. The role of external laws is to lead us to the One who can solve our sin problem, a Savior who provides the needed sacrifice for our sins. God wants to go deeper than our behavior; He wants a change in our hearts. When we are a part of the New Covenant, we know God not just intellectually but more importantly personally; we develop a close relationship with Him. God desires to write His law on our hearts. The question is, are we willing for Him to do this?
