John 20:29

29. Hast seen The word seen here implies the evidence not only of sight but of either or all the senses.

Have not seen, and yet have believed The visible tangible Christ will soon depart from the earth, to be seen no more. The doctrine and the power of his life and death will come forth to the faith of the world. The hearts and souls that rightly will to accept it, must do it by a faith that is above sight and above sense. Many will say, like Thomas, that they can only believe upon sensible demonstration. They will not be convinced but upon the highest possible proof; proof which shall meet their utmost exaction and leave doubt impossible. Some will do this in a spirit of low sensuality; some in a spirit of scientific indifference or intellectual pride. But all who in a true sense deserve to be saved will be saved; and none but those who deserve to be damned will be damned.

Blessed In what sense blessed? In no single, but in every divine sense. As faith in its full power procures, so this blessedness includes the full fruition of all that the Gospel offers or the atonement brings to man. Very wise were the words of Pfenninger, quoted by Stier: “Is not Thomas a pledge of all who, like him, are slow to believe, that every severe word spoken to unbelief refers to those who will not believe? As to this not-able and not-willing, God will judge.” That is, God will judge whether the not-able is an honest inability to believe when there is the spirit of faith, or whether it be a not-willing, deceiving the obstinate unbeliever into the false opinion that he is not able to believe.
