God and Law

All theology is theology proper.

Michael Horton says that human beings are created “wired” for the law: “It belongs to us by nature in creation, while the gospel is an announcement of good news in the event of transgression. It has to be preached, whereas the law belongs to the conscience of every person already. Therefore, the original relationship of humanity to God is one of law and love, not of grace and mercy.”

This makes grace, not law and judgment, the “strange work” of God. Grace comes, apparently, from the “left hand.” Is this not a fundamental reversal of Luther?
