Are there deep and secret things that are difficult to bring into the light? Yes. Does this dark world hide the evil deeds done by those who promote evil? Yes. Is there anyone powerful enough to reveal the truth?
When dealing with his own puzzling set of secrets, Daniel proclaimed this truth: “God-He reveals the deep and secret things: He knows what is in the darkness, and the light dwells with Him.” (Daniel 2:22) God goes deeper than the deep. His intelligence pierces those secret things. Darkness gives way before the power of His light.
God is Light, and light lives with Him. No secret is powerful enough to hide from the scrutiny of His light. He knows all. He reveals all.
