Charles H. Spurgeon on Psalms 30:5

As an apprentice holds out in hard labour and (it may be) bad usage for seven years together or more, and in all that time is serviceable to his master without any murmuring or repining, because he sees that the time wears away, and that his bondage will not last always, but he shall be set at large and made a freeman in the conclusion: thus should everyone that groaneth under the burden of any cross or affliction whatsoever, bridle his affections, possess his soul in patience, and cease from all murmuring and repining whatsoever, considering well with himself, that the rod of the wicked shall not always rest upon the lot of the righteous; that weeping may abide at evening, but joy cometh in the morning; and that troubles will have an end, and not continue for ever. John Spencer.
