(Isa 38:1-8) Hezekiah's sickness and recovery.
(Isa 38:9-22) His thanksgiving.
When we pray in our sickness, though God send not to us such an answer as he here sent to Hezekiah, yet, if by his Spirit he bids us be of good cheer, assures us that our sins are forgiven, and that, whether we live or die, we shall be his, we do not pray in vain. See Kg2 20:1-11.
We have here Hezekiah's thanksgiving. It is well for us to remember the mercies we receive in sickness. Hezekiah records the condition he was in. He dwells upon this; I shall no more see the Lord. A good man wishes not to live for any other end than that he may serve God, and have communion with him. Our present residence is like that of a shepherd in his hut, a poor, mean, and cold lodging, and with a trust committed to our charge, as the shepherd has. Our days are compared to the weaver's shuttle, Job 7:6, passing and repassing very swiftly, every throw leaving a thread behind it; and when finished, the piece is cut off, taken out of the loom, and showed to our Master to be judged of. A good man, when his life is cut off, his cares and fatigues are cut off with it, and he rests from his labours. But our times are in God's hand; he has appointed what shall be the length of the piece. When sick, we are very apt to calculate our time, but are still at uncertainty. It should be more our care how we shall get safe to another world. And the more we taste of the loving-kindness of God, the more will our hearts love him, and live to him. It was in love to our poor perishing souls that Christ delivered them. The pardon does not make the sin not to have been sin, but not to be punished as it deserves. It is pleasant to think of our recoveries from sickness, when we see them flowing from the pardon of sin. Hezekiah's opportunity to glorify God in this world, he made the business, and pleasure, and end of life. Being recovered, he resolves to abound in praising and serving God. God's promises are not to do away, but to quicken and encourage the use of means. Life and health are given that we may glorify God and do good.
