From The Christian Science Hymnal, 1938 edition
Be true and list the voice within,
Be true unto thy high ideal,
Thy perfect self, that knows no sin,
That self that is the only real.
God is the only perfect One:
My perfect self is one with Him;
So man is seen as God’s own son,
When Truth dispels the shadows dim.
True to our God whose name is Love,
We shall fulfill our Father’s plan;
For true means true to God above,
To self, and to our fellow man.
