There are certain words or phrases that John frequently uses that show the repeating themes of his Gospel: believe, witness, Comforter, life - death, light - darkness, I am... (as in Jesus is the "I Am"), and love.
Kuna baadhi ya maneno au misemo ambayo Yohana mara nyingi anatumia kuonyesha mada zake zinazo rudiwa katika Injili yake; amini, shahidi, Msaidizi, uzima - mauti, mwanga - giza, mimi... (kama kwamba Yesu ndiye "Mimi ndimi"), na upendo.
