Christ, only Christ, live then Thy life in me

I have been reading the book "Faithful Women and Their Extraordinary God".  Each chapter is a mini-biography of a Christian woman who was faithful to God's calling on her life...following him wherever he called her to go. You can read the book for free online and I highly recommend it!   I just finished the chapter about Helen Roseveare, a missionary doctor to the Congo.
This paragraph sums up what God taught her through her life there:

As Helen Roseveare stood by our fireplace and looked into their faces, she reached  backward toward the mantel and eased a longstemmed red rosebud from a tall vase. As she spoke, she broke off the thorns, the leaves, the petals, the green outer layer of stem—every elementvthat makes a rose a rose. All that was left was a lithe, straight shaft. The pieces that lay on the floor were not bad things. But, she explained, they had to be removed if she were going to make an arrow. God does this to us, she said. He removes everything—even innocent, good things—that hinders us from being the arrows that he will shoot for his purposes at his intended target.

This week I have also been reading and meditating on Romans 12.  I want my life to be a living sacrifice!  This poem was included at the end of the chapter on Helen Rosevear, and is a beautiful prayer in response... 

Not I, but Christ, be honored, loved, exalted,
Not I, but Christ, be seen, be known, be heard,
Not I, but Christ, in every look and action,
Not I, but Christ, in every thought and word.

Not I, but Christ, to gently soothe in sorrow,
Not I, but Christ, to wipe the falling tear,
Not I, but Christ, to lift the weary burden,
Not I, but Christ, to hush away all fear.

Not I, but Christ, no idle word e’er falling,
Christ, only Christ, no needless bustling sound,
Christ, only Christ, no self-important bearing,
Christ, only Christ, no trace of I be found.

Not I, but Christ, my every need supplying,
Not I, but Christ, my strength and health to be;
Christ, only Christ, for body, soul, and spirit,
Christ, only Christ, live then Thy life in me.

Christ, only Christ, e’re long will fill my vision;
Glory excelling soon, full soon I’ll see
Christ, only Christ, my every wish fulfilling—
Christ, only Christ, my all in all to be.
