When I was a youngster, we visited Mammoth Cave, Kentucky. Once inside a huge subterranean cavern, our guides turned out the lights. There was deep darkness. We could not see our hand in front of our face. The guide struck a match. We stood amazed at how such a tiny light pushed away the heavy black veil of darkness. We could see the vaulted ceiling and shimmering walls. I could see mom and dad.
The pages of the Bible are often dark and obscure. We need light from God. Look at the words of 2 Peter 1:19. "We have the prophetic word made more sure, to which you do well to pay attention as to a lamp shining in a dark place, until the day dawns and the morning star arises in your hearts."
The prophetic word is the Bible. We ought to pay attention to it and read it. There is light in the Bible. We also need light from the Spirit of God to derive light from the printed page. We need light from God to arise like the sun at dawn and illumine the words of Scripture we read in the Bible.
When this occurs, light comes on in our hearts and in our heads. We marvel. A little light from God can dispel a vast amount of darkness in our hearts.
