Then said He to Thomas, Reach hither thy finger, and behold My hands; and reach hither thy hand, and thrust it into My side: and be not faithless, but believing.” – John 20:27

Among us at this day we have many persons who are like Thomas -dubious, demanding signs and tokens, suspicious, and ofttimes sad. I am not sure that there is not a slight touch of Thomas in most of us. There are times and seasons when the strong man fails, and when the firm believer has to pause a while, and say, “Is it so?”

Admire his Master’s patience with him. He does not say, “If he does not choose to believe he may continue to suffer for his unbelief.” But no; He fixes His eye upon the doubter, and addresses Himself specially to him; yet not in words of reproach or anger. Jesus could bear with Thomas, though Thomas had been a long time with Him, and had not known Him. To put his finger into the print of the nails, and thrust his hand into His side, was much more than any disciple had a right to ask of his divine Master; and yet see the condescension of Jesus! Rather than Thomas should suffer from unbelief, Christ will let him take great liberties. Our Lord does not always act towards us according to His own dignity, but according to our necessity; and if we really are so weak that nothing will do but thrusting a hand into His side, He will let us do it. Nor do I wonder at this if, for our sakes, He suffered a spear to be thrust there, He may well permit a hand to follow. ~ C.H. Spurgeon
