Yahweh prepared a great fish to swallow up Jonah, and Jonah was in the belly of the fish three days and three nights.
To thank God, only in order to obtain fresh gifts from Him, would be but a refined, hypocritical form of selfishness. Such a formal act would not be thanks at all. We thank God, because we love Him, because He is so infinitely good, and so good to us, unworthy. Thanklessness shuts the door to His personal mercies to us, because it makes them the occasion of fresh sins of our’s. Thankfulness sets God’s essential goodness free (so to speak) to be good to us. He can do what He delights in doing, be good to us, without our making His Goodness a source of harm to us. Thanking Him through His grace, we become fit vessels for larger graces . “Blessed he who, at every gift of grace, returns to Him in whom is all fullness of graces; to whom when we show ourselves not ungrateful for gifts received, we make room in ourselves for grace, and become meet for receiving yet more.” But Jonah’s was that special character of thankfulness, which thanks God in the midst of calamities from which there was no human exit; and God set His seal on this sort of thankfulness, by annexing this deliverance, which has consecrated Jonah as an image of our Lord, to his wonderful act of thanksgiving.
