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.
But in another place in this Apostle's writings we read of 'the high calling of God in Christ Jesus.' Yes, there, as focussed into one strong voice, all the summonses are concentrated and gathered. For in Jesus Christ we see the possibilities of humanity realised, and we have the pattern of what we ought to be, and are called thereby to be. And in Christ we get the great motives which make this summons, as it comes mended from His lips, no longer the mere harsh voice of an authoritative legislator, but the gentle invitation, 'Come unto Me, ... and ye shall find rest unto your souls.' The summons is honeyed, sweetened, and made infinitely mightier when we hear it from His gracious lips. It is the blessed peculiarity of the Christian ideal, that the manifestation of the ideal carries with it the power to realise it. And just as the increasing strength of the spring sunshine summons the buds from out of their folds, and the snowdrops hear the call and force themselves through the frozen soil, so when Christ summons He inclines the ears that hear, and enables the men that own them to obey the summons, and to be what they are commanded. And thus we have 'the high calling of God in Christ Jesus.'
