I'm late here but will throw in my 2 cents if I may. The word of knowledge is a wonderful gift of the Holy Spirit given to a spirit filled believer in a moment of time for a specific purpose, problem or ministry. I appreciate the foregoing answers that show just a bit of the multitude of things about which God gives us inside info on. I had flown up to St. Louis on business and driven over into Illinois. When I returned for the trip home I was sitting in the packed out area my flight was to leave from. Waiting for my plane I was practicing my people watching past time when my gaze locked on a young man about my age. He'd come into the area and just leaned against a wall looking around. My gaze kept coming back to him again and again. Soon I realized that the Lord was talking to me about this man and the urging got so strong I had to get up and walk over to him. I introduced myself and said "I don't know you and you don't know me but I know something about you. I proceeded to share the things about this stranger that Jesus had told me. The man smiled faintly as I spoke and was slowly nodding his head back and forth. I told him that these were things that God had given me to say and what he did with them was between him and the Lord. He replied in shock and said "you know, you're the second person to come to me in three days and tell me the very same thing". God was certainly on that young man's trail. Harold Hill, writer of How to live like a king's kid, had this experience. A non Christian philosophy professor at a well known university didn't like Harold and put down his Christian beliefs at every opportunity. The man was a dyed in the wool pacifist and hated every form of violence. He gave a pacifist, anti gun lecture one night and God prompted Harold to go. As the man spoke the Lord gave Harold a word of knowledge about him. He was restrained by the Holy Spirit from using it until the right time. After going on and on about the evils of guns and weapons of all sorts he began to take questions from the audience. After most all of them were answered Harold raised his hand and asked the man again about his degree of dislike for guns of any kind for any purpose. The man went into his reasons and hatred for guns and their use for any reason. It was time now and Harold asked "is it true that you have a loaded rifle in your living room closet"? The man was struck silent and Harold repeated the question. He finally answered "yes" in a low voice and made his departure from the stage. God's word of knowledge had made a believer out of a pompous professor of philosophy and vain deceit. Instantly you just know something you didn't know before. It should be a normal thing for believers because our Holy counselor is ever with us. Harold Hill was a successful engineer and a millionaire but became a spirit filled Christian. One of his favorite sayings was "you don't need college for a word of knowledge".
