The second attack gave Him the opportunity of bringing out with great distinctness and vividness the witness of the Spirit of God to His work as Saviour of mankind. These Pharisees regarded His miracles as mere displays of power, apart altogether from the spirit of purity, mercy and grace so manifest in them all. It was only this narrowness of view that made it possible for them to imagine that the Spirit of evil, to whom of course no one could deny a certain measure of mere power, was behind them. How completely He answers their blasphemous suggestion by showing that the works He did, judged, not by the mere power they displayed, but by their whole spirit and tendency, were at the very opposite pole from the works of Satan, we plainly see; but the point now is the permanent value of His reasoning. At first sight it may seem to be quite out of date. Whoever dreams now of disposing of the works of Christ by attributing them to Satan? Let us not be over-hasty, however, in concluding that old objections are out of date. If we look closely at those regarded as the newest, we may find that they are but old ones in a new dress. What of the position taken by some intelligent men in our day, who candidly admit the power of Christianity to elevate and sanctify men, and yet set it down as false? As an illustration of this, we cannot do better than refer to a recent production[11] of the Agnostic School, in which there is the most emphatic testimony to the blessed power of Christianity in particular instances, followed by these most candid and generous words: "What needs admitting, or rather proclaiming, by agnostics who would be just, is that the Christian doctrine has the power of elevating and developing saintliness, which has had no equal in any other creed or philosophy." Yet the book in which that sentence occurs assumes throughout that this doctrine, which has had no equal in producing saintliness--a quality which in another place is described as "so lofty, so pure, so attractive, that it ravishes men's souls"--is untrue! Is, then, the argument of our Lord out of date? and is it too late to ask the old question, "Can Satan cast out Satan?"
