Read it through once

And then, “A stick, once fire from end to end; {105} Now, ashes save the tip that holds a spark! Yet, blow the spark, it runs back, spreads itself A little where the fire was: thus I urge The soul that served me, till it task once more What ashes of my brain have kept their shape, {110} And these make effort on the last o’ the flesh, Trying to taste again the truth of things”-- (He smiled)--“their very superficial truth; As that ye are my sons, that it is long Since James and Peter had release by death, {115} And I am only he, your brother John, Who saw and heard, and could remember all. Remember all! It is not much to say. What if the truth broke on me from above As once and oft-times? Such might hap again: {120} Doubtlessly He might stand in presence here, With head wool-white, eyes, flame, and feet like brass, The sword and the seven stars, as I have seen-- I who now shudder only and surmise ‘How did your brother bear that sight and live?’ {125}
