David Wilkerson emphasizes the importance of concise and sincere prayer, warning against the tendency to use long, wordy prayers that may lack genuine intent. He argues that God desires intelligent and respectful communication rather than empty clichés or attempts to impress Him with verbosity. Wilkerson encourages believers to be specific in their prayers, as this leads to clearer answers from God, and highlights the necessity of personal communion with the Lord. He stresses that true prayer requires dedication and transformation, urging that no one should approach prayer lightly or without preparation.
