C.S. Lewis on Imitating Christ
The Four Loves (Harcourt Trade: 1971; orig. 1960), p. 6.What is near Him by likeness is never, by that fact alone, going to be any nearer. But nearness of approach is, by definition, increasing nearness. An whereas the likeness is give to us — and can be received with or without thanks, can be used or abused — the approach, however initiated and supported by Grace, is something we must do. Creature are made in their varying ways images of God without their own collaboration or even consent. It is not so that they become sons of God. And the likeness they receive by sonship is not that of images or portraits. It is in one way more than likeness, for it is union or unity with God in will… [O]our imitation of God in this life — that is, our willed imitation as distinct from any of the likenesses which He has impressed upon our natures or states — must be an imitation of God incarnate: our model is the Jesus, not only of Calvary, but of the workshop, the roads, the crowds, the clamorous demands and surly oppositions, the lack of all peace and privacy, the interruptions. For this, so strangely unlike anything we can attribute to the Divine life in itself, is apparently not only like, but is, the Divine life operating under human conditions.
