Christ was neither ashamed nor afraid to own the purposes of his grace. He healed the poor man, though he knew that his enemies would take advantage against him for it. Let us not be drawn either from our duty or from our usefulness by any opposition. We may well be amazed, that the sons of men should be so wicked.
And as Charles Spurgeon says, "Not to save life is to destroy:"
See yonder poor wretches whose ship has gone down at sea, they have constructed a poor tottering raft, and have been swimming on it for days; their supply of bread and water is exhausted, and they are famishing, they have bound a handkerchief to a pole and hoisted it, and a vessel is within sight. The captain of the ship takes his telescope, looks at the object, and knows that it is a shipwrecked crew. "Oh!" says he to his men, "we are in a hurry with our cargo, we cannot stop to look after an unknown object; it may be somebody perishing, and it may not be, but however, it is not our business," and he keeps on his course. His neglect has murdered those who died on the raft.
