The immediate reference of these words is, of course, to the martyrdom of the Apostle Peter. Our Lord contrasts the vigorous and somewhat self-willed youth and the mellowed old age of His servant, and shadows forth his death, in bonds, by violence. And then He bids him, notwithstanding this prospect of the issue of his faithfulness, 'Follow Me.' Now I venture, though with some hesitation, to give these words a slightly different application. I see in them two pictures of youth and of old age, and a commandment based upon both. You young people are often exhorted to a Christian life on the ground of the possible approach of death. I would not undervalue that motive, but I seek now to urge the same thing upon you from a directly opposite consideration, the probability that many of you will live to be old. All the chief reasons for our being Christians are of the same force, whether we are to die to-night, or to live for a century. So in my text I wish you to note what you are now; what, if you live, you are sure to become; and what, in the view of both stages, you will be wise to do. 'When thou wast young thou girdedst thyself, and wentest whither thou wouldest. When thou shalt be old another shall gird thee, and carry thee whither thou wouldest not.' Therefore, 'Follow Me.' I. So, then, note the picture here of what you are. Most of you young people are but little accustomed to reflect upon yourselves, or upon the special characteristics and prerogatives of your time of life. But it will do you no harm to think for a minute or two of what these characteristics are, that you may know your blessings, and that you may shun the dangers which attach to them.
