Acts 20:31: Jesus the faithful pastors keep

Jesus the faithful pastors keep,
And stir us up to watch and pray,
As guardians of Thy lambs and sheep
To warn them both by night and day;
To' uncase their Aniinomian foe
And all his crafty windings show.

Remember Lord our griefs and fears
Lest Satan make our labours void,
Lest all Thy work (a work of years)
Be instantaneously destroy'd,
(A triumph for the Gnostic fiend,)
And shipwreck'd faith in ranting end.
