The Saviour is coming closer and closer to human need, dealing more and more thoroughly with the world's want and woe. If we look at it aright, we cannot but recognise it as really a greater thing to heal the deep disease of the soul, than to heal any or all of the diseases of the body, greater even than to still the storm or rule by superior power the spirits of evil. For here there is something more needed than power or skill, even though both be infinite. We have already had a glimpse of the need there was, even in taking away human sickness, that the Healer Himself should suffer. But deeper far is this necessity if the disease of the soul is to be reached. It is only the Lamb of God that can take away the sin of the world. These scribes were right for once when they made more of this claim than of any that had gone before, saying within themselves, "This man blasphemeth;" ... "Who can forgive sins but God only?"
How could He prove to them His power actually to forgive the man's sins? A demonstration of this is quite impossible; but He will come as near to it as may be. He has already recognised the faith of the bearers, and the penitence of the man himself; just as quickly He discerns the thoughts of the scribes, and gives them proof that He does so by asking them, "Wherefore think ye evil in your hearts?" Then, answering their thought (which was, "He is only saying it"), He replies in effect, "It is indeed as easy to say one thing as another, if saying is all; but that you may be sure that the saying of it is not all, I shall not repeat what I said before, the result of which from the nature of the case you cannot see, but something else, the result of which you shall see presently"; whereupon, turning to the sick of the palsy, He said: "Arise, take up thy bed, and go unto thine house. And he arose, and departed to his house." With characteristic reticence, the sacred historian says nothing of the feelings of the happy man as he hied him home with a double blessing beyond the power of words to tell.
Is it possible to imagine any better proof that could have been given of Christ's authority to forgive sins? Let those who have a horror of anything extraordinary suggest some way in which this assurance could have been given without any manifestation of superhuman power. If they cannot, why continue those unreasoning objections to the kind of proof He did give, when no other proof can be even suggested that would have at all suited the purpose?
The purpose was accomplished, so far at least as the people were concerned. Whether the scribes found some way of evading the conclusion, the Evangelist does not say; but he does say that "when the multitudes saw it, they marvelled," or, as the probably more correct version of the Revisers gives it, "they were afraid." This is true to nature, for now they knew that they stood in the presence of One Who could look them through and through, and touch them in their sorest spot; so it was natural that their first feeling should be one of awe. Still, they could not but be thankful at the same time that there was forgiveness within their reach; so quite consistently the narrative proceeds--And they "glorified God, which had given such power unto men."

Now that His power to deal with sin is made so apparent, it is time to let it be known that all sinners are welcome. Hence most appropriately there follows the call of one from among the most despised class to take a place among His closest followers. We can well understand how the modest Matthew, who never mentions anything else about himself, was glad to signalise the grace of the Master in seeking out the hated and despised publican. Not only does Christ welcome him, but consents to sit at meat with his former associates (ver. 10); and when the self-righteous Pharisee complains, He takes occasion to speak those memorable words, so full of warning to those who think themselves righteous, so full of comfort to those who know themselves sinners: "They that be whole need not a physician, but they that are sick.... I am not come to call the righteous, but sinners to repentance."
