Psalm 19 seems to be written with three main sections.  First, verses 1-6, we have a description of the creation of God.  David is reminding us how God’s attributes are demonstrated through nature.  Although we may not understand Him completely, we know that He is there as His voice “goes out into all the earth” (vs. 4).  Paul writes of God’s revelation in nature in Romans 1, “For since the creation of the world God’s invisible qualities – his eternal power and divine nature – have been clearly seen, being understood from what has been made so that men are without excuse.”

The second section, vs. 7-22, focuses on God’s revealed attributes through His law.  David lists all the wonderful qualities of the law of God!  This is where we can truly understand who God is.

The third section, vs. 12-14, brings it in a bit closer.  Here David asks for help in keeping a righteous life and asks that his prayers would be pleasing to God.  In light of how amazing God is, David responds apprioprately  – with humility and petition.
