19:7 converting the soul. While the “revelation” in God’s creation will condemn the soul, only the written revelation (described in Psalm 19:7-9) can convert or “restore” the soul. Note also the emphasis on the regenerating power of the Scriptures in such verses as II Timothy 3:15-17, I Peter 1:23-25, etc.
19:8 statutes of the LORD. While the physical world gives mighty testimony to the existence of God, and His power in creation, only the written Word can give testimony to the power of God in salvation. Note that the Scriptures are “perfect,” “sure,” “right,” “pure,” “forever,” “true,” and “righteous altogether.” In a sense, God does have two books, but His written revelation is superior to His physical creation (note Psalm 138:2), and the latter can only be truly understood as expounded by the former. Many modern evangelicals are making the serious mistake of trying to make Scripture conform to current “science.” It should be the other way around.
