A man named Hubert Mitchell memorized the entire New Testament. As a former missionary in his sixties, he spent his days in downtown Chicago, going from office building to office building. Inside he would ask secretaries if he could have five minutes with their boss to talk about a personal matter. Frequently he would be ushered into the boss's office, and he would say, "I only have five minutes, but I want to ask you, did you read your Bible before you came to work this morning?"

The boss would look at him as if he were crazy, and say, "No."

Hubert would smile and answer, "Sir, you sure missed a blessing, didn't you? I'd just like to share with you what God spoke about to me in the Bible this morning." He would open a New Testament and hand it to the boss, and say, "Let's start right here." Then Hubert would sit back and start quoting it word for word.

The boss would listen, amazed. After five minutes, Hubert would say, "My time's up and I've got to go. Wasn't that a blessing?" On most occasions the boss would ask him to stay longer, and they would talk.

Hubert Mitchell led men to Christ all over downtown Chicago that way, because God's word was burning in his heart.
