“But even now I know that whatever You ask of God, God will give You.” – John 11:22

If you are in the same position as Martha, I can bring out several points of likeness which should encourage you to persevere. You, mother, have prayed for your boy; you, father, have pleaded for your girl; you, dear wife, have been much in prayer for your husband; you beloved teacher, have frequently brought your class before God; and yet there is a bad case pressing upon your mind, and your heart is heavy about some dear one, whose condition seems hopeless. I want you to believe that now, even now, Christ can grant your prayer, and save that soul; that now, even now, He can give you such a blessing that the past delay shall be more than recompensed to you.

There is one, for instance, in whom we are deeply interested, and we can say that the case has caused great sorrow. So, Martha could have said of Lazarus. “Blessed master”, she might have said, “my brother took the fever”- (for I should think it was a fever that he had) -“and I watched him; I brought cold water from the well, and I laved his burning brow; I was by his bedside all night. Nobody knows how my heart was wrung with anguish as I saw the hot beaded drops upon his brow and tried to moisten his parched tongue and lips. I sorrowed as though I was about to die myself; but in spite of all that, I believe even now that Thou canst help me; even now.” Alas! There are many griefs in the world like this. A mother says, “Nobody knows what I have suffered through that son of mine. I shall die of a broken heart because of his conduct.” “No one can tell,” says the father, “what grief that daughter of mine has caused me. I have sometimes wished that she had never been born.” There have been many, many such stories told into my ear, in which a beloved one has been the cause of anguish and agony untold to gracious, loving hearts. To those so sorely troubled I now speak. Can you believe that even now the living Intercessor is “mighty to save”? It may be that you are at this moment trembling on the verge of the blessing you so long have sought. God give you faith to grasp it “even now”! ~ C.H. Spurgeon
