Here are the words:

1
From my spirit within flows a fountain of life—
  The Triune God flowing in me;
God the Father’s the source, Christ the Son is the course,
  And the Spirit imparts life to me.
 	
Lord, I treasure the sweet flow of life,
  And my soul-life at last I lay down;
O Lord, deepen the pure flow of life;
    At Your coming may life be my crown.

2
In the fresh, tender grass Jesus makes me lie down;
  He leads me by waters of rest;
No more struggle and strain; all self-effort is vain;
  In the flow I am perfectly blessed.

3
Jesus called me one day to the Holiest Place,
  To live in His presence divine;
Hallelujah, I’ve heard an encouraging word:
  “Abide—you’re a branch in the vine.”
