IV. In the last two verses of this chapter we have two passages relating to this story which were omitted in the narrative of it here, but which we had 2 Kings xx., and therefore shall here only observe two lessons from them:—1. That God's promises are intended not to supersede, but to quicken and encourage, the use of means. Hezekiah is sure to recover, and yet he must take a lump of figs and lay it on the boil, v. 21. We do not trust God, but tempt him, if, when we pray to him for help, we do not second our prayers with our endeavours. We must not put physicians, or physic, in the place of God, but make use of them in subordination to God and to his providence; help thyself and God will help thee. 2. That the chief end we should aim at, in desiring life and health, is that we may glorify God, and do good, and improve ourselves in knowledge, and grace, and meetness for heaven. Hezekiah, when he meant, What is the sign that I shall recover? asked, What is the sign that I shall go up to the house of the Lord, there to honour God, to keep up acquaintance and communion with him, and to encourage others to serve him? v. 22. It is taken for granted that if God would restore him to health he would immediately go up to the temple with his thank-offerings. There Christ found the impotent man whom he had healed, John v. 14. The exercises of religion are so much the business and delight of a good man that to be restrained from them is the greatest grievance of his afflictions, and to be restored to them is the greatest comfort of his deliverances. Let my soul live, and it shall praise thee.
