“Oh that I were as in months past.”- Job 29:2

For the most part the gracious Shepherd leads His people beside the still waters, and makes them to lie down in green pastures; but at times they wander through a wilderness, where there is no water, and they find no city to dwell in. Hungry and thirsty, their soul fainteth within them, and they cry unto the Lord in their trouble. Though many of His people live in almost constant joy, and find that religion’s ways are ways of pleasantness, and all her paths are peace, yet there are many who pass through fire and through water: men do ride over their heads, (and) they endure all manner of trouble and sorrow…

One of the causes of this mournful state of things is defect in prayer; and of course the cure lies somewhere next door to the cause. You are saying, “Oh that I were as in months past!” Come, my brother; we are going into the very root of the matter. One reason why it is not with you as in months past is this: you do not pray as you once did. Nothing brings such leanness into a man’s soul as want of prayer. It is well said that a neglected closet is the birth-place of all evil. All good is born in the closet, all good springeth from it; there the Christian getteth it; but if he neglecteth his closet, then all evil comes of it. No man can progress in grace if he forsakes his closet. I care not how strong he may be in faith. ~ C.H. Spurgeon
