David Wilkerson emphasizes the unwavering nature of God's promises, asserting that they are sealed with an oath and cannot be broken. He encourages believers to actively lean on God's Word and trust in His promises, even when they do not receive direct communication from Him. Wilkerson illustrates this trust through the example of David, who, despite not seeing the fulfillment of God's words, confidently rested on the promise of salvation for his house. The sermon highlights that true intimacy with God comes from surrendering our need to understand everything and simply relying on His faithfulness. Ultimately, Wilkerson reassures that God's promises are sufficient for all our needs, allowing us to face life's challenges with confidence.
