For I know that my Redeemer liveth… – Job 19:25
The marrow of Job’s comfort it seems to me lays in that little word “My.” “I know that MY Redeemer lives.” Oh, to get hold of Christ! I know that in His offices He is precious, but, dear friends, we must have a part in Him before we can really enjoy Him. What is honey in the wood to me, if like the fainting Israelites, I dare not eat. It is honey in my hand, honey on my lips, which enlightens my eyes like those of Jonathan. What is gold in the mine to me? Men are beggars in Peru and beg their bread in California; it is gold in my purse which will satisfy my necessities, purchasing the bread I need. So, what is a kinsman if he is not a kinsman to me? What is a Redeemer that does not redeem me, an avenger who will never stand up for my blood, of what avail were such? But Job’s faith was strong and firm in the conviction that the Redeemer was his. Dear friends, dear friends, can all of you say, “I know that my Redeemer lives.” The question is simple and simply put; but oh, what solemn things hang upon your answer! “Is He MY Redeemer?” I charge you: rest not, be not content until by faith you can say, “Yes, I cast myself upon Him; I am His, and therefore He is mine.” I know that full many of you, while you look upon all else that you have as not being yours, yet can say, “My Redeemer is mine.” He is the only piece of property which is really ours. We borrow all else—the house, the children, no, much more—our very body we must return to the Great Lender. But Jesus, we can never leave, for even when we are absent from the body, we are present with the Lord, and I know that even death cannot separate us from Him! The body and soul are with Jesus truly even in the dark hours of death, in the long night of the sepulcher, and in the separate state of spiritual existence. Beloved, have you Christ? It may be you hold Him with a feeble hand; you half think it is presumption to say, “He is my Redeemer;” yet remember, if you have but faith as a grain of mustard seed, that little faith entitles you to say, and say now, “I know that MY Redeemer lives.” ~ C.H. Spurgeon
