Traherne is addressing Christ directly in this passage, acknowledging and rejoicing in his closeness to Christ, accepting that suffering unites Men – he of course means men and women – and Christ, now suffering on the cross for me.
What shall I do for Thee, O Thou preserver of Men?
Live, Love, and Admire; and learn to become such unto Thee as Thou unto me. O Glorious Soul; whose comprehensive
understanding at once contains all Kingdoms and Ages! O Glorious Mind! Whose love extendeth to all creatures! O miraculous and eternal Godhead, now suffering on the cross for me: As Abraham saw thy Day and was glad, so didst Thou see me and this Day from all Eternity, and seeing me wast Gracious and Compassionate towards me. (All transient things are permanent in God.) Thou settest me before Thy face forever. O let me this day see Thee, and be united to Thee in Thy Holy Sufferings. Let me learn, O God, such lessons from Thee, as may make me wise, and blessed as an Angel of GOD!
First Century 62.
