Oh, that I were as in months past, as in the days when God preserved me; When His candle shined upon my head, and when by His light I walked through darkness; As I was in the days of my youth, when the secret of God was upon my tabernacle… – Job 29:2-4

It is unprofitable to read these words of Job, and say, “Just so, that is how I feel,” and then continue in the same way. If a man has neglected his business, and so has lost his trade, it may mark a turn in his affairs when he says, “I wish I had been more industrious;” but if he abides in the same sloth as before, of what use is his regret? If he shall fold his arms and say, “Oh that I had dug that plot of land; oh that I had sown that field;” no harvest will come because of his lamentations. Up, man, up and labor, or you will have the sluggard’s reward, rags and poverty will still be your portion. If a man be in declining health, if drunkenness and riot have broken down his constitution, it may mark a salutary reform in his history if he confesses his former folly; but if his regrets end in mere expressions, will these heal him? I trow not. So neither will a man, affected by spiritual decline, be restored by the mere fact of his knowing himself to be so. Let him go to the beloved Physician, drink of the waters of life again, and receive the leaves of the tree which are for the healing of the nations. Inactive regrets are insincere. If a man really did lament that he had lost communion with God, he would seek to regain it. If he doth not seek to be restored he is adding to all his former sins this of lying before God, in uttering regrets that he does not feel in his soul.

Remember, many have been on Job’s dunghill, who knew nothing of Job’s God; many have imitated David in his sins, who never followed him, in his repentance. They have gone from their sin into hell by the way of presumption, whereas David went from it to heaven by the road of repentance and forgiveness. Never let us; merely because we feel some uneasiness within, conclude that this suffices…Up, men, and with all the strength that God’s Holy Spirit can give you, strive to drive out these traitors from your bosom, for they are robbing your soul of her best treasures. ~ C.H. Spurgeon
