David Wilkerson addresses the dangerous resentment many Christians harbor against God, stemming from unmet expectations and unanswered prayers. He shares the story of David Flood, a missionary who, after suffering great loss and disappointment, turned bitter towards God, believing his sacrifices were in vain. Wilkerson emphasizes that such anger can lead to spiritual desolation, as seen in the lives of many believers and ministers who feel abandoned by God. He encourages those struggling with bitterness to seek healing and restoration, reminding them that God has a purpose for their pain and will reward their faithfulness. Ultimately, the message is one of hope and the importance of releasing anger to experience God's grace.
