But He answered her not a word. – Matthew 15:23

Christ delays in order to increase the blessing itself. While we wait, the blessing becomes bigger, and our hands become stronger to hold it when it does come. You may be sure that our blessed Lord will give you a comfortable answer; for you do not know that He has been sustaining you while you have been pleading, and as yet have received no answer? Did you ever notice, when Joseph’s brethren went down into Egypt, that he made himself strange to them, and spoke to them roughly, and put them in prison? But in spite of that, there was one thing he did: when they went back to Jacob, he filled their sacks for them. He would not smile upon them, but he would not starve them; and at last, it is said, “Joseph could not refrain himself,” and he “made himself known unto his brethren. He was obliged to show his love at last; but even before he did that, he always filled their sacks for them. Christ will deal with you in like manner; while you are waiting, He will not let you die. Oh, in what wonderful ways did the Lord support me when, through weary years, I was seeking His face! I could not say that I had any comfort that I dared to call my own, and yet there flowed into my soul, somehow, a secret power that enabled me still to hope, and still to hold on; for that I now desire to bless His name, and I tell it for the encouragement of any who may be in soul-trouble as I was. Keep on seeking His grace, dear friend. Believe still; for He must give you a comfortable answer one of these days.~ C.H. Spurgeon
