For the Son of man ... - This is a second reason why we should not despise Christians. That reason is, that the Son of man came to seek and save them. He came in search of them when lost; he found them; he redeemed them. It was the great object of his life; and, though they may be obscure and little in the eye of the world, yet that cannot be an object of contempt which the Son of God sought by his toils and his death.
Son of man - See the notes at Matthew 8:19-20.
That which was lost - Property is lost when it is consumed, mislaid, wasted, sunk in the ocean, etc. - when we have no longer the use of it. Friends are lost when they die - we enjoy their and happiness. He is useless to society. So all people are “lost.” They are wicked, miserable wanderers from God. They are lost to piety, to happiness, to heaven. These Jesus came to save by giving his own life a ransom, and shedding his own blood that they might be recovered and saved.
