“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” (Jeremiah 31:33)

God told the prophet Jeremiah of a new covenant that He would make with His people in the future. That future is now. The law is no longer written on stone tablets, but it is written by grace on the hearts of those who have believed and received the righteousness of Christ.
