I will declare the decree: the LORD has said to me, You are my Son; this day have I begotten you.
I. THE GENERAL MATTER OF THE SERMON. It is a law. What manner of law? A law to be preached, as other laws used not to be. A law concerning what God said. Which is the reason why it is to be preached. Not a law at large, but a statute law (Elchok), which but by publishing none can take notice of.
II. THE TEXT ITSELF. Or the body of the law. In these words, "Thou art My Son, this day have I begotten Thee. The points in it are five. Of a son. Of My Son, (that is) the Son of God. Genui, the Son of God begotten. Hodie, the Son of God this day begotten. And "dixit genui," (that is) "dicendo genuit," begotten only by saying. Only said the word and it was done, and the word became flesh.
III. HOW CAN THIS (THOU ART MY SON) BE CALLED A LAW? It does not look like one. There be but two laws —
1. Lex fidei; a law limiting what to believe of Him: of His person, His nature, and His offices.
2. Lex factorum; setting out first, what He doth for us; and then, what we are to do for Him. What He doth for us is, convey all filial rights. What we are to do for Him is, return to Him all filial duties.
