"Oh, God! God! God! You are really alive! You really healed me! How could You cure me this neatly? How could You get rid of all my diseases at once?" This is the story of the life and ministry of a world-renowned Korean evangelist Dr. Jaerock Lee. When modern medicine proved ineffective and he was still suffering from many kinds of illnesses, his sister brought him to Christ and his body was restored to health and wholeness. From that moment he met the living God, he has loved God first of all and dedicated his life to the kingdom and righteousness of God. And through numerous vowed and fasting prayers, he received the healing power of God to cure people of their various afflictions and diseases, even of cancer. Dr. Lee delivers a message of faith and holiness not just to save people's afflicted bodies but to save something much more valuable-their souls. And he always emphasizes that some believers, though they profess faith with their lips and seem to lead a believing life outwardly, cannot gain salvation on the last judgment day if they do not take that belief deep into their heart and practice the Word of God in action. The works of one's faith are extremely important for his everlasting salvation. The unchanging love for God and unceasing walk of faith with the Lord of a sincere believer and servant of God, which are described in this testimonial book are a signpost to good children of God.
