He speaketh still in the present tense. These words were not fulfilled six weeks after this, for he conversed with his disciples forty days after his resurrection, Acts 1:3; but Christ was now shortly coming, therefore he saith, I come. And, saith he, while I am in the world, I speak these things; I put up this prayer, that the joy of my people may not be diminished by my going from them, but that when they can no longer (as hitherto) rejoice in my bodily presence with them, they may yet rejoice that I am ascended to my Father, that they stand commended to the care of thee, my Father, by this my last prayer.
