Grace and Truth

The Gospel of John begins by introducing key themes that are expanded in the body of the book - Life , Light , Witness , Truth , and Grace . Jesus is the Light of the world , the source of Grace and Truth , the True Tabernacle , the only born Son of God , and the only one who has seen the Father. The introduction concludes by declaring that he is the only one who is qualified to interpret the unseen God since he alone has seen Him.
