1:15-24 St. Paul was wonderfully brought to the knowledge and faith of Christ. All who are savingly converted, are called by the grace of God; their conversion is wrought by his power and grace working in them.

He instantly prepared to obey, without hesitating as to his worldly interest, credit, ease, or life itself. And what matter of thanksgiving and joy is it to the churches of Christ, when they hear of such instances to the praise of the glory of his grace, whether they have ever seen them or not! They glorify God for his power and mercy in saving such persons, and for all the service to his people and cause that is done, and may be further expected from them.
