Yes, prayer is strong, and God is good

Yes! prayer is strong, and God is good;
Man is not made for endless ill;
The offending soul, in darkest mood,
Hath yet a hope, a refuge still.

Thou, God, wilt hear; these pangs are meant
To heal the spirit, not destroy;
And even remorse, for chastening sent,
When Thou commandest, works for joy.
