David Wilkerson emphasizes that feelings of inadequacy and discouragement are common, but they should not lead us to doubt God's love and support. He challenges the notion that self-deprecation is humility, asserting that it actually insults God's work in us. Instead, we are called to rise above self-pity and recognize our identity as loved and chosen by God. Wilkerson encourages believers to recall God's past faithfulness and to declare strength in the face of weakness, as God empowers us to overcome our struggles. Ultimately, he reminds us that true faith endures and is bolstered by God's promises.
