Solomon comes to experience; he puts his hand upon the right spot. It is knowing his "own sore" and his "own grief." You may know another man's; that will not profit you. You may read of experience in books, love to hear experimental ministers, and will hear no others; and yet not know your "own sore," your "own grief." Like a physician who may know the symptoms of every malady, and yet not have one malady of his own; so you may hear described every symptom of every disease, and yet be untouched by one.
But the man for whom Solomon's prayer is, he that knows and feels, painfully feels, his "own sore" and his "own grief," whose heart is indeed a grief to him, whose sins do indeed trouble him. How painful this sore often is! how it runs night and day! how full of ulcerous matter, and how it shrinks from the probe! Most of the Lord's family have a "sore," each some tender spot, something perhaps known to himself and to God alone, the cause of his greatest grief. It may be some secret slip he has made, some sin he has committed, some word he has spoken, or some evil thing he has done. He has been entangled, and entrapped, and cast down; and this is his grief and his sore which he feels, and that at times deeply before God. For such Solomon prays: he casts his net upon the right side of the ship; and says, "Then hear thou from heaven thy dwelling-place, and forgive, and render unto every man according unto all his ways, whose heart thou knowest; for thou only knowest the hearts of the children of men." Yes; God alone knows the heart; he knows it completely, and sees to its very bottom.
