(4.) That it was the lengthening out of his opportunity to glorify God in this world, which he made the business, and pleasure, and end of life. [1.] If this sickness had been his death, it would have put a period to that course of service for the glory of God and the good of the church which he was now pursuing, v. 18. Heaven indeed praises God, and the souls of the faithful, when at death they remove thither, do that work of heaven as the angels, and with the angels, there; but what is this world the better for that? What does that contribute to the support and advancement of God's kingdom among men in this state of struggle? The grave cannot praise God, nor the dead bodies that lie there. Death cannot celebrate him, cannot proclaim his perfections and favours, to invite others into his service. Those who go down to the pit, being no longer in a state of probation, nor living by faith in his promises, cannot give him honour by hoping for his truth. Those that lie rotting in the grave, as they are not capable of receiving any further mercy from God, so neither are they capable of offering any more praises to him, till they shall be raised at the last day, and then they shall both receive and give glory. [2.] Having recovered from it, he resolves not only to proceed, but to abound, in praising and serving God (v. 19): The living, the living, he shall praise thee. They may do it; they have an opportunity of praising God, and that is the main thing that makes life valuable and desirable to a good man. Hezekiah was therefore glad to live, not that he might continue to enjoy his royal dignity and the honour and pleasure of his late successes, but that he might continue to praise God. The living must praise God; they live in vain if they do not. Those that have been dying and yet are living, whose life is from the dead, are in a special manner obliged to praise God, as being most sensibly affected with his goodness. Hezekiah, for his part, having recovered from this sickness, will make it his business to praise God: "I do it this day; let others do it in like manner." Those that give good exhortations should set good examples, and do themselves what they expect from others. "For my part," says Hezekiah, "the Lord was ready to save me; he not only did save me, but he was ready to do it just then when I was in the greatest extremity; his help came in seasonably; he showed himself willing and forward to save me. The Lord was to save me, was at hand to do it, saved me a the first word; and therefore," First, "I will publish and proclaim his praises. I and my family, I and my friends, I and my people, will have a concert of praise to his glory: We will sing my songs to the stringed instruments, that others may attend to them, and be affected with them, when they are in the most devout and serious frame in the house of the Lord." It is for the honour of God, and the edification of his church, that special mercies should be acknowledged in public praises, especially mercies to public persons, Ps. cxvi. 18, 19. Secondly, "I will proceed and persevere in his praises." We should do so all the days of our life, because every day of our life is itself a fresh mercy and brings many fresh mercies along with it; and, as renewed mercies call for renewed praises, so former eminent mercies call for repeated praises. It is by the mercy of God that we live, and therefore, as long as we live, we must continue to praise him, while we have breath, nay, while we have being. Thirdly, "I will propagate and perpetuate his praises." We should not only praise him all the days of our life, but the father to the children should make known his truth, that the ages to come may give God the glory of his truth by trusting to it. It is the duty of parents to possess their children with a confidence in the truth of God, which will go far towards keeping them close to the ways of God. Hezekiah, doubtless, did this himself, and yet Manasseh his son walked not in his steps. Parents may give their children many good things, good instructions, good examples, good books, but they cannot give them grace.
