Charles H. Spurgeon on Psalms 139:16

A skilful architect before he builds draws a model, or gives a draught of the building in his book, or upon a table; there he will show you every room and contrivance: in his book are all the parts of the building written, while as yet there are none of them, or before any of them are framed and set up. In allusion to architects and other artisans, David speaks of God, In thy book all my members were written; that is, Thou hast made me as exactly as if thou hadst drawn my several members and my whole proportion with a pen or pencil in a book, before thou wouldst adventure to form me up. The Lord uses no book, no pen to decipher his work. He had the perfect idea of all things in himself from everlasting; but he may well be said to work as by pattern, whose work is the most perfect pattern. —Joseph Caryl.
