No Scar?

Dr. Stephen Olford writes the following words concerning Amy Carmichael:

Amy Carmichael was an Irish missionary who spent 53 years in South India without a furlough. She founded the Dohnavur Fellowship, a refuge for children in mortal danger. For a great part of her life she was bed-ridden with an incapacitating affliction but she never let up in serving others by her prayers, writings and personal counseling. The Spirit of God, to whom she was totally committed, has wafted the fragrance of her life across the Christian world.

Her life and ministry are best reflected in this challenging poem:

Hast thou no scar?
No hidden scar on foot, or side, or hand?
I hear thee sung as mighty in the land;
I hear them hail thy bright, ascendant star.
Hast thou no scar?

Hast thou no wound?
Yet I was wounded by the archers; spent,
Leaned Me against a tree to die; and rent
By ravening beasts that compassed Me,
I swooned.
Hast thou no wound?
No wound?

No scar?
Yet, as the Master shall the servant be,
And piercèd are the feet that follow Me.
But thine are whole; can he have followed far
Who hast no wound or scar?
