Theres are light, we chase it in the tunnel for whole of life.

Gensis 1:1-5 :

1.In the beginning God created the heaven and the earth.

2.And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.

3.And God said, Let there be light: and there was light.

4.And God saw the light, that it was good: and God divided the light from the darkness.

5.And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.
