Why?

Lord, if I love Thee and Thou lovest me,
  Why need I any more these toilsome days;
  Why should I not run singing up Thy ways
Straight into heaven, to rest myself with Thee?
What need remains of death-pang yet to be,
  If all my soul is quickened in Thy praise;
  If all my heart loves Thee, what need the amaze,
Struggle and dimness of an agony?--
Bride whom I love, if thou too lovest Me,
  Thou needs must choose My Likeness for thy dower:
    So wilt thou toil in patience, and abide
  Hungering and thirsting for that blessed hour
When I My Likeness shall behold in thee,
    And thou therein shalt waken satisfied.
