1:13-17 The mariners rowed against wind and tide, the wind of God's displeasure, the tide of his counsel; but it is in vain to think of saving ourselves any other way than by destroying our sins. Even natural conscience cannot but dread blood-guiltiness. And when we are led by Providence God does what he pleases, and we ought to be satisfied, though it may not please us. Throwing Jonah into the sea put an end to the storm. God will not afflict for ever, He will only contend till we submit and turn from our sins. Surely these heathen mariners will rise up in judgment against many called Christians, who neither offer prayers when in distress, nor thanksgiving for signal deliverances. The Lord commands all creatures, and can make any of them serve his designs of mercy to his people. Let us see this salvation of the Lord, and admire his power, that he could thus save a drowning man, and his pity, that he would thus save one who was running from him, and had offended him. It was of the Lord's mercies that Jonah was not consumed. Jonah was alive in the fish three days and nights: to nature this was impossible, but to the God of nature all things are possible. Jonah, by this miraculous preservation, was made a type of Christ; as our blessed Lord himself declared, Mt 12:40.
