Matthew 17: Satan the instrument defies

Satan the instrument defies,
Unarm'd with that almighty power.
Which cast him flaming from the skies.
And reigns throughout his dreary hour:
But quits us at our Lord's command;
For Christ he never can withstand.

Some desperate souls the God of grace
Reserves to make His goodness known.
He cures them in peculiar ways.
He all performs Himself alone
Without His ministers, to show
They without Him can nothing do.

Instructed thus, from man we cease,
Through ministers to Jesus look.
Our only refuge in distress.
Who all our sin and sickness took,
Whose power effects whate'er He wills,
Whose mercy in an instant heals.
