From The Christian Science Hymnal, 1932 edition
Walk in the light, so thou shalt know
That fellowship of love
His spirit only can bestow
Who reigns in light above.
Walk in the light, and thou shalt find
Thy heart made truly His,
Who dwells in cloudless light enshrined,
In whom no darkness is.
Walk in the light, and thou shalt own
Thy darkness past away,
Because that light on thee hath shone
In which is perfect day.
Walk in the light, and thou shalt see
Thy path, though thorny, bright;
For God by grace shall dwell with thee,
And God Himself is Light.
