David Wilkerson emphasizes the urgency of living out our faith in a world filled with fear and calamity. As believers face increasing unrest, they are called to stabilize their faith and demonstrate an unshakable trust in God, serving as a living testimony to the world. While many are consumed by anxiety, Christians are encouraged to look up and rejoice, knowing their redemption is near. Wilkerson stresses that the world needs to see faith in action, not just hear sermons about it, as this illustrated faith can provide hope to the lost. Ultimately, our steadfastness in trials can affirm our testimony and inspire others to seek God.
