"Why can I not follow thee even now?" (dia ti ou dunamai soi akolouqein arti;). The use of arti (right now, this minute) instead of nun (at this time, verse 1 John 36 ) illustrates the impatience of Peter. I will lay down my life for thee (ten psuchn mou uper sou qhsw). Future active indicative of tiqhmi. Peter, like the rest, had not yet grasped the idea of the death of Christ, but, like Thomas ( 1 John 11:16 ), he is not afraid of danger. He had heard Christ's words about the good shepherd ( 1 John 10:11 ) and knew that such loyalty was the mark of a good disciple.
