Jonah stands as the great example of human weakness in the chosen instruments of God's hand.
Take the story--his shrinking from the message given him. We know not why; but perhaps from faint-hearted fear, or from a sense of his unworthiness and unfitness for the task. His own words about God as long-suffering seem to suggest another reason, that he feared to go with a message of judgment which seemed to him so unlikely to be executed by the long-suffering God. If so, then what made him recreant was not so much fear from personal motives as intellectual perplexity and imperfect comprehension of the ways of God. Then we hear of his pitiable flight with its absurdity and its wickedness. Then comes the prayer which shows him to have been right and true at bottom, and teaches us that what makes a good man is not the absence of faults, but the presence of love and longing after God. Then we see the boldness of his mission. Then follows the reaction from that lofty height, the petulance or whatever else it was with which he sees the city spared. Even the mildest interpretation cannot acquit him of much disregard for the poor souls whom he had brought to repentance, and of dreadful carelessness for the life and happiness of his fellows.
Now Jonah's behaviour is but a specimen of the vacillations, the alternations of feeling which beset every man; the loftiest, the truest, the best. Moses, David, Solomon, Elijah, John the Baptist, Peter, Luther, Cranmer. And it is full of instruction for us.
Then we turn to the contrast in Christ's perfect obedience and faithfulness in His prophetic office. In Him is no trace of shrinking even when the grimness of the Cross weighed most on His heart. No confusion of mind as to the Father's will, or as to the union in Him of perfect righteousness and infinite mercy, ever darkened His clear utterances or cast a shadow over his own soul. He was never weakened by the collapse that follows on great effort or strong emotion. He never failed in his mission through lack of pity.
But there is no need to draw out the comparison. We look on all God's instruments, and see them all full of faults and flaws. Here is one stainless name, one life in which is no blot, one heart in which are no envy, no failings--one obedience which never varied. He says of Himself, I do always those things which please Him,' and we, thinking of all the noblest examples of virtue that the world has ever seen, and seeing in them all some speck, turn to this whole and perfect chrysolite and say, Yes! a greater than they!'
