Therefore, the sisters sent to Him, saying, “Lord, behold, he whom You love is sick.”…Then Martha, as soon as she heard that Jesus was coming, went and met Him…Now Martha said to Jesus…“But even now I know that whatever You ask of God, God will give You.” – John 11:3,,21,22

You say, “I have prayed long for a dear friend, and I believed, some time ago, that my prayer was heard, and that there was a change for the better; indeed, there was an apparent change; but it came to nothing.” You are just like Martha. She kept saying to herself, “Christ will come. Brother is very ill, but Jesus will come before he dies; I know He will. It cannot be that He will stay away much longer; and when He comes, Lazarus will soon be well.” Day after day, Mary and she sent their messenger to look toward the Jordan, to see if Jesus was not coming. But He did not come. It must have been a terrible disappointment to both these sisters; enough to stagger the strongest faith that had ever had in the sympathy of Christ. But Martha got the better of it, and she said, “Even now, though disappointed so bitterly, I believe that Thou canst do whatsoever Thou wilt.” Learn from Martha, my discouraged brother. You thought that your friend was converted, but he wanted to go back again; you thought that there was a real work of grace upon his heart, but it turned out to be a mere disappointment, and disappeared, like the mist in the sun. But can you not believe over the head of your disappointment, and say, “I believe even now, even now”? Blessed shall your faith be, if it gets so far. ~ C.H. Spurgeon
