May I beg you carefully to judge every preacher, not by his gifts, not by his elocutionary powers, not by his status in society, not by the respectability of his congregation, not by the prettiness of his church, but by this – does he preach the word of truth, the gospel of your salvation? If he does, your sitting under his ministry may prove to you the means of begetting faith in you. But if he does not, you cannot expect God's blessing.
