David Wilkerson emphasizes that through times of affliction, God prepares us for greater purposes beyond mere survival. He encourages believers to recognize that their struggles are not in vain, as God intends for them to use their experiences to help others facing similar challenges. Wilkerson highlights the importance of sharing our testimonies of God's faithfulness with the next generation, as seen in the psalms and the life of Paul. He reminds us that our best work is still ahead, and we are called to be seasoned veterans who demonstrate God's strength and hope to those around us. Ultimately, our trials serve to further the gospel and inspire others to trust in God's promises.
