In Runo was Life, ind that Life was don Xround dis Men. Dor Xround xrounds dær Light but dær Light has not understood Ot.

“In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning. Through him all things were made; without him nothing was made that has been made. In him was life, and that life was the light of men. The light shines in the darkness, but the darkness has not understood it.” John 1:1-5 (New International Version) http://www.biblegateway.com/passage/?search=john%201:1-5&version=NIV
