In this book, Witness Lee presents eight cases from the Gospel of John that cover the needs of eight kinds of people—the moral, the immoral, the impotent, the hungry, the thirsty, the sinful, the blind, and the dead. Through these cases, we can see the true condition of mankind. These cases present more than just our condition and need, however. They also reveal the redemption of Christ, showing that the eternal, uncreated, incorruptible, and unfading life of God is the answer to all of our needs.
