Therefore his sisters sent unto Him, saying, Lord, behold, he whom Thou lovest is sick…When He had heard therefore that he was sick, He abode two days still in the same place where He was. – John 11:3, 6

No doubt when Mary and Martha sent to tell Jesus they looked to see Lazarus recover as soon as the messenger reached the Master; but they were not gratified. For two days the Lord remained in the same place, and not till He knew that Lazarus was dead did He speak of going to Judea. This teaches us that Jesus may be informed of our trouble, and yet may act as if He were indifferent to it. We must not expect in every case that prayer for recovery will be answered, for if so, nobody would die who had chick or child, friend or acquaintance to pray for him. In our prayers for the lives of beloved children of God we must not forget that there is one prayer which may be crossing ours, for Jesus prays, “Father, I will that they also, whom Thou hast given Me, be with Me where I am, that they may behold My glory.” We pray that they may remain with us, but when we recognize that Jesus wants them above, what can we do but admit His larger claim and say, “Not as I will, but as Thou wilt”? In our own case, we may pray the Lord to raise us up, and yet though He loves us He may permit us to grow worse and worse, and at last to die. Hezekiah had fifteen years added to his life, but we may not gain the reprieve of a single day. Never set such store by the life of any one dear to you, or even by your own life, as to be rebellious against the Lord. If you hold the life of any dear one with too tight a hand, you are making a rod for your own back; and if you love your own earthly life too well, you are making a thorny pillow for your dying bed. Children are often idols, and in such cases their too ardent lovers are idolaters. We might as well make a god of clay, and worship it, as the Hindus are said to do, as worship our fellow-creatures, for what are they but clay? Shall dust be so dear to us that we quarrel with our God about it? If our Lord leaves us to suffer, let us not repine. He must do that for us which is kindest and best, for He loves us better than we love ourselves. ~ C.H. Spurgeon
