Law on Stone vs. Heart
Driving home: This cup is, it stands for, it represents, it sets forth my commitment to secure the blessings of the new covenant. It is the new covenant in my blood.
Martin contrasts God writing the Ten Commandments on stone, which has no life or ability to respond, with His promise in the new covenant to write His laws on the mind and heart, signifying an internal, living response.
Do you see that in the passage? I will put my laws into their mind and on their heart. Also, will I write them? And obviously there are overtones from what God did when he originally gave the summary of the moral law in the ten words.
