David Wilkerson emphasizes that the disasters occurring on earth serve as warnings from God about the imminent return of Jesus. He explains that these events are a divine countdown, meant to awaken humanity to the urgency of preparation for the coming kingdom. Despite the frightening nature of these signs, Wilkerson reassures believers that God is in control and encourages them to face challenges with faith and confidence. He reminds us that God has not given us a spirit of fear, but rather one of power, love, and a sound mind. Ultimately, these times should inspire hope and readiness for redemption.
