Fear not, thou worm Jacob… and thy Redeemer… – Isaiah 41:14

Did you never notice that a promise always seems all the sweeter for having Jesus in it? All the promises are yea and amen in Him; but when a promise mentions the name of the Redeemer, it imparts a peculiar blessedness to it… The grace of God the Trinity, shining through the man Christ Jesus, becomes a mellow, soft light, so that mortal eye can bear it. My God, I could not drink from Thy well, if Thou hadst not put there the earthen pitcher of my Saviour; but with Him living waters from Thy sacred well I draw…  Christ Jesus cast into the river of God, makes all the streams more sweet; and when the believer sees God in the person of the Saviour, he then sees the God whom he can love, and to whom with boldness he can approach. Surely I love this promise all the better, because I think I see my Saviour, with His hand all bleeding, stamping His hand upon it, and saying, “And thy Redeemer,” and there is the blood mark left upon the promise. It does seem to me as if when God uttered that promise to the poor worm Jacob, Jesus Christ could not be still. He heard His Father say, “Fear not, worm Jacob;” and He saw the poor worm, with his head on one side, with his eyes all flowing with tears, with his heart palpitating with terror, and his arms folded in dismay; and when His Father had said, “Fear not,” He stepped from behind, and whispered in a voice more soft than the voice of His Father, “Fear not, worm Jacob, it is God that speaks;” and then the soft voice says, “And it is thy Redeemer that speaks too.” He says, “Fear not.” He who loves thee, who knows thee, who has felt what thou feelest, who has passed through the woes which thou art now enduring- He who is thy Kinsman and thy Brother, He also says “Fear not, worm Jacob.” Oh, it is sweet, it is precious to look upon that word, as spoken by our Redeemer.~ C.H.
