Many years ago I suffered from a stomach ulcer. Even If I ate food which was a little too salty, spicy, or sour, I had diarrhea right after that. Later, even after eating a very light soup, I had to go to the bathroom. According to the doctor, my stomach was as thin as a paper so that if I ate the wrong food it might burst. In three months, I lost about 15 lbs. When I thought about preparing for the summer retreat and preaching as a major speaker, I realized that I could not go on like this. One morning, I prayed to the Lord. "God, I know there is nothing that You can not do. Please cure me of my stomach ulcer." After I prayed, Mark, chapter 11 came to my mind.
"Therefore I say unto you, What things soever ye desire, when ye pray, believe that ye receive them, and ye shall have them."(Mark 11:24)
In accordance with that verse, if I believed that I was cured, I obviously could eat foods such as rice, beef, kimchi, soy bean paste and coffee, because I was cured. However, my real condition was having diarrhea even if I had a spoonful of soup. I felt that if I ate those things, as my doctor had said, my stomach would burst. To have faith, I had to eat anything. With no faith, it seemed impossible for me to teach faith to the members of my church when I was not living by faith as a pastor. "God, I believe. I will believe if You cure me." Nevertheless, God said, "Believe, then I will cure you."
I reopened the Bible and thought it over. "Let"s say that I believe; if I believe and eat rice, kimchi, soy bean paste and drink coffee, am I going to live or die?" As I looked at my situation, I was likely to die. But according to the Bible, I had already been cured. I had thoughts in my heart, "God never lies if I believe. He will never let me die." "God, I believe that I am cured. Now I am well." It will be easy to have a belief if I can see the signs of my recovery. But it was really difficult to believe in the Word when I was still sick. I kept trying to believe after knowing that I was cured. That was believing the result but not believing the Word. Believing in God is believing in His Word. "God, forgive me what I did not believe."

That morning, many pastors came, so my wife cooked beef and soy bean paste soup. She prepared a bowl of porridge, seaweeds, and a few dried-shrimps for me at the corner of the table. But I sat at the table which had the biggest bowl of rice. My wife was surprised and asked me, "Is it alright for you to eat rice?" I said, "My stomach has already been cured so I will be fine," and ate my fill. Just after I finished the meal, I started to feel pain in my stomach so I went to the bathroom. Satan whispered, "Why are you having pain in your stomach? Did not you say that you had been cured? You may die." I had nothing to say. Thinking I might die if I continued to eat like this, I had a picture in my head that I died because my stomach had burst and my wife and children were crying next to my dead body. And the more thoughts came to my mind. After a while, the Lord spoke to my heart. "The word of God is living. You have been cured." "How can I still suffer from the diarrhea if I was cured?" I questioned. "If God said that you were cured, then you were cured." Those words came to my mind and my heart became peaceful. "Right. Sick but cured!" I did not have to fight with Satan any more. My struggling was finished. I had been cured.
I had rice for lunch. I still had to go to the bathroom but my heart was still in peace. I was invited to a buffet for dinner at a hotel. I had five helping. I filled myself up but I did not have to go to the bathroom. Next morning, as I woke up, my stomach was fine. I found that I had been cured completely. Since then, whatever I ate, I didn"t have any trouble with my stomach and now I can go anywhere in the world to preach the gospel.
