This is the judgment, that the light has come into the world, and men loved the darkness rather than the light; for their works were evil.

 The man who reacts in hostility to Jesus has loved the darkness rather than the light. The terrible thing about a really good person is that he always has a certain unconscious element of condemnation in him. It is when we compare ourselves with him that we see ourselves as we are. Alcibiades, the spoilt Athenian man of genius, was a companion of Socrates and every now and again he used to break out: "Socrates, I hate you, for every time I meet you, you let me see what I am." The man who is engaged on an evil task does not want a flood of light shed on it and him; but the man engaged on an honourable task does not fear the light.
