Acts 4:14: They could say nothing against it

The greatest miracles of grace
Can only silence and confound,
Not change the persecuting race,
Unless the Lord their conscience wound,
His efficacious love exert
And break the unbeliever's heart.

The dire effects of envious pride
Even now our blind opposers show:
The proofs stand forth on every side,
The sinners heal'd they see and know,
And can no longer, Lord, gainsay,
Yet still refuse the truth to' obey.
