Obedience

Trust him in the common light;
Trust him in the awesome night;
Trust him when the earth doth quake:
Trust him when thy heart doth ache;
Trust him when thy brain doth reel
And thy friend turns on his heel;
Trust him when the way is rough,
Cry not yet, It is enough!
But obey with true endeavour,
Else the salt hath lost his savour.
