Law and Gospel
The Law is everything that God Demands.
Or you could say it is everything His Holiness demands and these are the things that dont burn up in his holy refiners fire. Pure and True.
The Gospel is what He Gives, and what He gives in the Gospel is what He demands in the Law.
And Jesus Christ through His works satisfies these demands of God and His holiness.
This is the Good News.
Grace and Peace,
