For the Son of God to empty himself and become poor meant a laying aside of glory; a voluntary restraint of power; an acceptance of hardship, isolation, ill-treatment, malice, and misunderstanding; finally, a death that involved such agony – spiritual, even more than physical – that is his mind nearly broke under the prospect of it. It meant love to the uttermost for unlovely men, who “through his poverty, might become rich.” This Christmas message is that there is hope for a ruined humanity – hope of pardon, hope of peace with God, hope of glory – because at the Father’s will Jesus Christ became poor and was born in a stable so that thirty years later he might hang on a cross. It is the most wonderful message that the world has ever heard, or will hear.
We talk glibly of the “Christmas spirit,” rarely meaning more by this than sentimental jollity on a family basis. But what we have said makes it clear that the phrase should in fact carry a tremendous weight of meaning. It ought to mean the reproducing in human lives of the temper of him who for our sakes became poor at the first Christmas. And the Christmas spirit itself ought to be the mark of every Christian all the year round.
It is our shame and disgrace today that so many Christians – I will be more specific: so many of the soundest and most orthodox Christians – go through this world in the spirit of the priest and the Levite in our Lord’s parable, seeing human needs all around them, but (after a pious wish, and perhaps a prayer, that the Lord might meet those needs) averting their eyes and passing by on the other side. That is not the Christmas spirit. Nor is it the spirit of those Christians – alas, they are many – whose ambition in life seems limited to building a nice middle-class Christian home, and making nice middle-class Christian friends, and bringing up their children in nice-middle class Christian ways, and who leave the submiddle-class sections of the community, Christian and non-Christian, to get on by themselves.
The Christmas spirit does not shine out in the Christian snob. For the Christian spirit is the spirit of those who, like their Master, live their whole lives on the principle of making themselves poor – spending and being spent – to enrich their fellow humans, giving time, trouble, care and concern, to do good to others – and not just their own friends – in whatever way there seems need….”You know the grace of our Lord Jesus Christ, that though he was rich, yet for your sakes he became poor, so that you through his poverty might become rich (2 Cor 8:9).”
