For I know that my Redeemer liveth, and that He shall stand at the latter day upon the earth…Whom I shall see for myself, and mine eyes shall behold, and not another; though my reins be consumed within me. – Job 19:25, 27

Beloved, is everything uncertain with you in this world? Of course it is, for it is so with everybody. But does it appear to be more uncertain with you than it does with anybody else? Does your business seem to be slipping away, and every earthly comfort be threatening to disappear? Even if it is so, there is, nevertheless, something that is certain, something, that is stable,-Jesus your Redeemer lives. Rest on Him, and you will never fail. Let your faith in Him be firm, and confident; you cannot be too fully established in the belief that Jesus, who once died, has left the grave, to die no more, and that you, in Him, must also live eternally. Something may be wrong with you, for the next few days or weeks, but all is right with you for ever, and “all’s well that ends well.” There may be some rough water to be crossed between here and the fair havens of eternal felicity, but all is right there for ever and ever. There may be losses and crosses, there may be tossings and shipwrecks, but all is right for ever with all who are in Christ Jesus. “Some on boards, and some on broken pieces of the ship,”-but all who are in Christ Jesus shall escape “safe to land.” There are uncertainties innumerable, but there is this one certainty: “Israel shall be saved in the Lord with an everlasting salvation: ye shall not be ashamed nor confounded world without end.” Spring on this rock, man! If you are struggling in the sea, just now, and waves of sin and doubt beat over you, leap on to this rock: Jesus lives. Trust the living Christ; and, because He lives, you shall live also. I could cheerfully take my place with Job, if I might be able to say as confidently as he did, “I know that my Redeemer liveth;” and if you, as a poor sinner, are trusting wholly and only in Christ, then He is your Redeemer, and you are saved for ever. If He is the only hope that you have, and you cling to Him as the limpet clings to the rock, then all is right with you for ever, and you may know that He is your Redeemer as surely as Job knew that He was his. The Lord bless you, for Jesus Christ’s sake! Amen. ~ C.H. Spurgeon
