I. When he prayed (v. 1): Then Jonah prayed; then when he was in trouble, under the sense of sin and the tokens of God's displeasure against him for sin, then he prayed. Note, When we are in affliction we must pray; then we have occasion to pray, then we have errands at the throne of grace and business there; then, if ever, we shall have a disposition to pray, when the heart is humbled, and softened, and made serious; then God expects it (in their affliction they will seek me early, seek me earnestly); and, though we bring our afflictions upon ourselves by our sins, yet, if we pray in humility and godly sincerity, we shall be welcome to the throne of grace, as Jonah was. Then when he was in a hopeful way of deliverance, being preserved alive by miracle, a plain indication that he was reserved for further mercy, then he prayed. An apprehension of God's good-will to us, notwithstanding our offences, gives us boldness of access to him, and opens the lips in prayer which were closed with the sense of guilt and dread of wrath.
