That might of faith, O Lord! bestow,
Which cannot ask in vain;
Which will not let the angel go
Until the prayer it gain.
On me the faith divine bestow
Which doth the mountain move;
And all my spotless life shall show
The omnipotence of love.
And, Father, when I doubt that I
Can live, and sin no more;
Then if on Thee I dare rely,
The faith shall bring the power.
