[As for the public, many] are very incompetent judges of doctrine; but they can form a tolerable judgment of a writer's spirit. They know that meekness, humility and love are the characteristics of a Christian temper. . . . They are quick-sighted to discern when we deviate from such a spirit, and avail themselves of it to justify their contempt of our arguments. The Scriptural maxim, that "the wrath of man worketh not the righteousness of God," is verified by daily observation. If our zeal is embittered by expressions of anger, invective, or scorn, we may think we are doing service of the cause of truth, when in reality we shall only bring it into discredit. The weapons of our warfare, and which alone are powerful to break down the strongholds of error, are not carnal, but spiritual; arguments fairly drawn from Scripture and experience, and enforced by such a mild address, as may persuade our readers, that, whether we can convince them or not, we wish well to their souls, and contend only for the truth's sake; if we can satisfy them that we act upon these motives, our point is half gained; they will be more disposed to consider calmly what we offer.
