Now, my two texts bring out two aspects which have to be taken in conjunction. The one of them speaks about the present life, and lays it as an imperative obligation on all Christian people to be worthy of their Christianity, and the other carries us into the future and shows us that there it is they who are 'worthy' who attain to the Kingdom. So I think I shall best bring out what I desire to emphasise if I just take these two points--the Christian calling and the life that is worthy of it, and the Christian heaven and the life that is worthy of it. I. The Christian calling and the life that is worthy of it. 'I beseech you that ye walk worthy of the vocation wherewith ye are called.' Now, that thought recurs in other places in the Apostle's writings, somewhat modified in expression. For instance, in one passage he speaks of 'walking worthily of the God who has called us to His kingdom and glory,' and in another of the Christian man's duty to 'walk worthily of the Lord unto all pleasing.' There is a certain vocation to which a Christian man is bound to make his life correspond, and his conduct should be in some measure worthy of the ideal that is set before it. Now, we shall best understand what is involved in such worthiness if we make clear to ourselves what the Apostle means by this 'calling' to which he appeals as containing in itself a standard to which our lives are to be conformed. Suppose we try to put away the technical word 'calling' and instead of 'calling' say 'summons,' which is nearer the idea, because it conveys the notions more fully of the urgency of the voice, and of the authority of the voice, which speaks to us. And what is that summons? How do we hear it? One of the other Apostles speaks of God as calling us 'by His own glory and virtue,' that is to say, wherever God reveals Himself in any fashion, and by any medium, to a man, the man fails to understand the deepest meaning of the revelation unless his purged ear hears in it the great voice saying, 'Come up hither.' For all God's self-manifestation, in the creatures around us, in the deep voice of our own souls, in the mysteries of our own personal lives, and in the slow evolution of His purpose through the history of the world, all these revelations of God bear in them the summons to us that hear and see them to draw near to Him, and to mould ourselves into His likeness. And thus, just as the sun by the effluence of its beams gathers all the ministering planets, as it were, round its feet, and draws them to itself, so God, raying Himself out into the waste, fills the waste with magnetic influences which are meant to draw men to nobleness, goodness, God-pleasingness, and God-likeness.
