Before sin entered the human heart, man's only authority was his Creator. It never occurred to him that there was another source of counsel. His thinking was in sync with God's desires, and disagreement simply did not exist. Doing God's will was his pure and continual joy.However, when that pristine relationship went sour, other people became sources of authority and counsel. David's first word (v.1) was to turn away from evil and human guidance, and then he focused on the true source of excellent living—the Word! For us who were created by God for His glory, eternal prosperity comes through delighting in His Word and doing His will.​
