One day when Rutherford was in the Spirit in his silent prison, whether in the body or out of the body, he was caught up into Paradise to see the beauty of his Lord, and to hear his little daughter singing Glory. And among the thousands of children that sang around the throne he told young Cardoness that he saw and heard little Barbara Gordon, whose death had broken every heart in Cardoness Castle. 'I give you my word for it,' wrote Rutherford to her broken-hearted father, 'I saw two Anwoth children there, and one of them was your child and one of them was mine.' And when another little voice was silenced in the Castle to sing Glory in heaven, Rutherford could then write to young Cardoness all that was in his heart; he could not write too plainly now or too often. Not that you are to suppose that they were all saints now at Cardoness Castle, or that all their old and inherited vices of heart and character were rooted out: no number of deaths will do that to the best of us till our own death comes; but it was no little gain towards godliness when Rutherford could write to young Gordon, now old with sorrow, saying, 'Honoured and dear brother, I am refreshed with your letter, and I exhort you by the love of Christ to set to work upon your own soul. Read this to your wife, and tell her that I am witness for Barbara's glory in heaven.' We would gladly shut the book here, and bring the Cardoness correspondence to a close, but that would not be true to the whole Cardoness history, nor profitable for ourselves. We have buried children, like John Gordon; and, like him, we have said that it was good for us to be sore afflicted; but not even the assurance that we have children in heaven has, all at once, set our affections there, or made us meet for entrance there. We feel it like a heavy blow on the heart, it makes us reel as if we had been struck in the face, to come upon a passage like this in a not-long-after letter to little Barbara Gordon's father: 'Ask yourself when next setting out to a night's drinking: What if my doom came to-night? What if I were given over to God's sergeants to-night, to the devil and to the second death?' And with the same post Rutherford wrote to William Dalgleish telling him that if young Cardoness came to see him he was to do his very best to direct and guide him in his new religious life. But Rutherford could not roll the care of young Cardoness over upon any other minister's shoulders; and thus it is that we have the long practical and powerful letter from which the text is taken: 'Put off a sin or a piece of a sin every day.'
