Context

“It makes a difference to people who have never heard of Him. It is like dropping into a glass of water one drop of something which gives a new taste or a new colour to the whole lot. But, of course, none of these illustrations really works perfectly. In the long run God is no one but Himself and what He does is like nothing else. You could hardly expect it to be otherwise. What, then, is the difference which He has made to the whole human mass? It is just this; that the business of becoming a son of God, of being turned from a created thing into a begotten thing, of passing over from the temporary biological life into timeless ‘spiritual’ life, has been done for us.” source
