As the world’s Redeemer, Christ was constantly confronted with apparent failure. He, the messenger of mercy to our world, seemed to do little of the work He longed to do in uplifting and saving. Satanic influences were constantly working to oppose His way. But He would not be discouraged. Through the prophecy of Isaiah He declares, “I have labored in vain, I have spent My strength for nought, and in vain: yet surely My judgment is with the Lord, and My work with My God.... Though Israel be not gathered, yet shall I be glorious in the eyes of the Lord, and My God shall be My strength.” Isaiah 49:4, 5L. It is to Christ that the promise is given, “Thus saith the Lord, the Redeemer of Israel, and His Holy One, to Him whom man despiseth, to Him whom the nation abhorreth; ... thus saith the Lord: ... I will preserve Thee, and give Thee for a covenant of the people, to establish the earth, to cause to inherit the desolate heritages; that Thou mayest say to the prisoners, Go forth; to them that are in darkness, Show yourselves.... They shall not hunger nor thirst; neither shall the heat nor sun smite them: for He that hath mercy on them shall lead them, even by the springs of water shall He guide them.” Isaiah 49:7-10L.
