50:15 For a moment, heaven was opened to the guilty and hardened Nero, and its peace and purity seemed desirable. That moment the invitation of mercy was extended even to him. But only for a moment was the thought of pardon welcomed.

No ray of light from heaven was ever again to penetrate the darkness that enveloped him. Soon he was to suffer the retributive judgments of God.
