Jesus, personification of The Word, personification of The Light. The Light that entered the World; The World which existed through IT; The Light that all must eventually recognise.
This likeness represents, Jesus as Christ, The Good Shepherd.
John 11 27-29: ‘My sheep hear my voice, and I know them, and they follow me; And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand. My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father’s hand.’
