How may we acquire the same confidence? What is the evidence of our interest in Job’s living Redeemer? The nature and effects of the change which has taken place in our hearts. You that “were sometime darkness, are now light in the Lord;” have been “called out of darkness into his marvellous light;” and can say—“One thing I know, that whereas I was once blind, now I see.” “The carnal mind is enmity against God;” but those that are born of the Spirit love God; and love and hatred are not so much alike, that you cannot tell by which principle you are governed. While the strong man armed kept the palace, his goods were in peace; but when a stronger than he came and cast him out, there was a warfare commenced between the old man and the new. You were formerly dead in trespasses and sins; but are now alive to God, through our Lord Jesus Christ. You were once destitute of faith in the Redeemer; but now you believe in him, and rely upon his righteousness alone, as the ground of your acceptance and salvation. How can you experience such a transformation, and know nothing of the matter? As well might the sick, when Christ healed them—as well might the blind, when Christ opened their eyes—as well might the dead, when Christ raised them to second life from the bed, the bier, or the grave—have been ignorant of the mighty change. In the word of God, we have the testimony of many who had obtained the assurance of faith. “I know that my Redeemer liveth, and that he shall stand upon the earth at the latter day”—was the testimony of Job. “The Lord is my rock, and my fortress, and my deliverer, and the horn of my salvation, in whom I will trust”—was the testimony of David. “I will greatly rejoice in the Lord; my soul shall be joyful in God; for he hath clothed me with the garments of salvation; he hath covered me with the robe of righteousness”—was the testimony of Isaiah. “I know in whom I have believed, and am persuaded that he is able to keep that which I have committed unto him against that day”—was the testimony of the apostle Paul. “We know that we are of God; we know that we have passed from death unto life; we know that when he shall appear, we shall be like him, for we shall see him as he is”—was the testimony of John, “the beloved disciple.”
