Acts 21:20: And they are all zealous of the law

Happy the man through special grace
From old prejudging errors free,
Errors of birth, or sect, or place,
Habit, or nature's bigotry,
Which with a blind misguided zeal
The heart of true believers fill.

O might I none but Jesus know,
Baptized with pure celestial fire!
Saviour, Thy fervent mind bestow,
And bless me with Thine own desire,
That all Thy perfect law may prove
Of life, and liberty, and love.
