When Jesus said, “I am the light of the world,” he was defining himself. He was saying, “I know who I am.” At least 18 times in the Bible, Jesus said, “I am” and then gave a description. He described himself as the door, the bread of life, the way, the truth, the resurrection, and the life. Over and over, he defined himself. Jesus knew who he was (and still is), and as a result, he was not under pressure.
