The laws of the spirit are more real than the natural laws. God's laws are primarily principles to release blessing, not rules to be obeyed to gain right standing with God.
The Psalmist talks of one whose greatest delight is in the law of the Lord. This delight allows one to discover new aspects of the nature of God (hidden in each law) to behold and worship. The end result of this delighting is a transformed life that prospers in every endeavor. His experience can be our experience, and this book unlocks the blessings hidden in the spiritual realm.
