But this shall be the covenant that I will make with the house of Israel; After those days, says the LORD, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.
All Commentaries on Jeremiah 31:33 Go To Jeremiah 31
Augustine of Hippo
AD 430
Isn’t the finger of God to be understood as being the Holy Spirit? Read the gospel, and see that where one Evangelist has the Lord saying, “If I with the Spirit of God cast out demons,” another says, “If I with the finger of God cast out demons.” So if that law too was written by the finger of God, that is by the Spirit of God, the Spirit by which Pharaoh’s magicians were defeated, so they said, “This is the finger of God.” So if that law too, indeed because that law too was composed by the Spirit of God, that is, by the finger of God, why can it not be said of it, “For the law of the Spirit of life in Jesus Christ has delivered you from the law of sin and death”?… So, the “law of the Spirit of life,” written on the heart, not on stone, in Christ Jesus, in whose person was celebrated the ultimately real and genuine Passover “has delivered you from the law of sin and death.”
