The sun is the only light that has no darkness

 1 John 1:1-5 KJV

That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life; 

[2] (For the life was manifested, and we have seen it, and bear witness, and shew unto you that eternal life, which was with the Father, and was manifested unto us;) 

[3] That which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly our fellowship is with the Father, and with his Son Jesus Christ.

[4] And these things write we unto you, that your joy may be full. 

[5] This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all.

To The Unknown God. Whom therefore ye ignorantly worship, him declare I unto you.…

Acts 17King James Version (KJV) 

For thou bringest certain strange things to our ears: we would know therefore what these things mean.

21 (For all the Athenians and strangers which were there spent their time in nothing else, but either to tell, or to hear some new thing.)

22 Then Paul stood in the midst of Mars' hill, and said, Ye men of Athens, I perceive that in all things ye are too superstitious.

23 For as I passed by, and beheld your devotions, I found an altar with this inscription

24 God that made the world and all things therein, seeing that he is Lord of heaven and earth, dwelleth not in temples made with hands;

25 Neither is worshipped with men's hands, as though he needed any thing, seeing he giveth to all life, and breath, and all things;

26 And hath made of one blood all nations of men for to dwell on all the face of the earth, and hath determined the times before appointed, and the bounds of their habitation;

27 That they should seek the Lord, if haply they might feel after him, and find him, though he be not far from every one of us:

28 For in him we live, and move, and have our being; as certain also of your own poets have said, For we are also his offspring.

29 Forasmuch then as we are the offspring of God, we ought not to think that the Godhead is like unto gold, or silver, or stone, graven by art and man's device.

To be a rock and not to roll

The final line in the immensely popular Led Zeppelin song "Stairway to Heaven" is no accident. The stairway is an allegory for "the way to get somewhere." The lyrics are essentially scripture, cleverly adapted by the band to form a song. I'm sure they had no idea what they were saying. Anyway, that's not the point. Every line in the song can be interpreted as another form of gospel, so to speak. Let's focus this discussion on the last line: "To be a rock and not to roll." Why not to roll? The words "rock" and "stone" are critical allegorical keywords in the Bible, meant to signify "stillness" — the stillness of meditation. When Peter builds the House of God on a rock, he is referring to meditation. When Jacob uses a rock as a pillow, it signifies meditation. When David slays Goliath with five smooth stones, it symbolizes overcoming his greatest mental challenges in the stillness of meditation. Rock and roll is the antithesis of meditation. To be a rock and "not" to roll signifies the stillness of meditation.

Jacob

Genesis 28:18

And Jacob rose up early in the morning, and took the stone that he had put for his pillows, and set it up for a pillar, and poured oil upon the top of it.

And Jacob took a stone, and set it up for a pillar.

Genesis 31:46

And Jacob said unto his brethren, Gather stones; and they took stones, and made an heap: and they did eat there upon the heap.

Peter

And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it.

David

And David put his hand in his bag, and took thence a stone, and slang it, and smote the Philistine in his forehead, that the stone sunk into his forehead; and he fell upon his face to the earth.

And David commanded to gather together the strangers that were in the land of Israel; and he set masons to hew wrought stones to build the house of God.
