Acts 15:5: Certain of the sect of the Pharisees which believed, &c

Faith, which when it comes, sets free
And purifies the heart,
Doth not perfect purity
And light at once impart:
Errors and mistakes remain,
And various prepossessions blind:
Purged by Christ from every stain
We know not all His mind.

Justified through faith alone
We may in Babel dwell,
May in words the truth disown
Which in our hearts we feel;
Still as saved by works and grace
To Moses and his law incline,
Add our human righteousness
To righteousness Divine.
