Q. In the new testament when it says the ‘law will be written on our hearts’ what is this law that’s being talked about? How do we know if we’re obeying it if we don’t know clearly what it is? The NT says the greatest law is to love God and to Love others. I just feel confused as He also says if you love me you will obey my laws.
A. Some form of that phrase appears 3 times in the New Testament. In Romans 2:15 Paul was saying that every human intuitively knows the requirements of God’s law (the commandments). In Hebrews 8:10 and Hebrews 10:16 the writer was quoting Jeremiah 31:33 saying this will happen to Israel when they receive the New Covenant. When the Lord says His law will be written on our hearts, He means we’ll automatically want to obey the commandments and won’t have to think about doing it. We show our love for God by obeying the first four commandments and we love one another by obeying the other six.
