     24. But none of these things move me, neither, &c.—In this noble expression of absolute dedication to the service of Christ and preparedness for the worst that could befall him in such a cause, note (1) his jealousy for the peculiar character of his mission, as immediately from Christ Himself on which all the charges against him turned; (2) the burden of that Gospel which he preached—GRACE; it was "the Gospel of the Grace of God."
