There was one thing at which our Lord himself marveled while here on the earth, and that was unbelief. Many things cause great surprise to His disciples and the multitudes that attended Him, but the most surprising thing to Christ himself was the blindness and hardness of the human heart.
This so hindered Him in His own country that: "He could there do no mighty work there, save that He laid his hands upon a few sick folk, and healed them. And He marveled because of their unbelief." (Mark 6:5-6)
Also when He healed the centurion's servant (Luke 7:2-9) He marveled, not because the centurion had faith, but because His own people had less faith than did this Roman.
Unbelief is a stranger thing than is the mightiest miracle ever performed; because there has been a cause for every miracle, but for unbelief there is no cause.
It is not strange that God can do most astonishing things, for He is omnipotent and omniscient; but it is strange indeed that man will not believe His word. It is so strange as to be absolutely without reason.
