All humans carry a sword and a shield.
We strike out at and critique others with our verbal, philosophical, political, social or literal swords. We block and defend ourselves from criticism with our good intentions, mimising excuses, self-justifying reasoning. Our shields.
It’s not that we should never defend ourselves, and I don’t know if we should be surprised that people and nations frequently want to have at least some kind of readiness to respond to violence. It’s just that the sword and shield become a way of being. They shape us into people whose tendency is to critique others and defend ourselves.
This even happens within ourselves, psychologically. We divide ourselves into parts: parent / child, good / bad, the rebel / the law, or what have you… One part of us critiques the other part, and the other part defends itself. We don’t have to suffer from multiple-personality disorder to relate to the experience of feeling simultaneously innocent and righteous on the one hand and victimised and full of self pity on the other hand. It’s the sword and shield again. Just directed inward.
Christianity offers a way of life where we trust God to be our sword and shield.
We don’t need to take up the sword against others and sort them out. (Or ourselves.) God is just. (And merciful.) The biblical wisdom is that God almost always does this in his usual way – by delegation. Natural law, imperfect human governments, communal or relational systems. Injustice has its day, but eventually gets toppled. When we try to rush the process with our swords, we end up becoming what we hate.
We also don’t need to overly defend or protect ourselves from critique. God is our fortress, tower, shield, and defender. The great irony is that when I live in the freedom of not worrying what might happen to me (gossip, violence, theft, you name it), those things don’t have any power over me. I trust that God will deal with them as he will, and when he will. Ultimately, the biblical narrative promises a final justice that will heal all wounds and restore all things. I can choose to take comfort in that.
Christ – at Christmas and at all times – comes to us asking for an exchange.
He wants our swords and shields, and offers us a cross and a towel.
I am offered a cross. An instrument of death and violence to myself. I am not expected to do what Jesus alone could do – atone for the sins of the world. I am invited, expected or even commanded to follow his way. To ‘take up my cross and follow’ him. To live sacrificially is not the way of self-loathing – constantly criticizing, punishing and judging myself. As the cliche truth goes, it’s not “thinking less of myself, but thinking of myself less.”
And this leads to the towel. I am to become a servant. Not a show off servant. Not “Hey everyone, I’m just going to pick up this piece of rubbish… aren’t I a great person….” Not “Hey everyone, look how pissed off I am about social injustice… I probably hate oppressors more than anyone I know…” Not this. Real service. Service that can go unnoticed. Uncelebrated.
The world is full of divided politics, communities, families and selves. If we’re honest, we’ll be able to see how we participate in wleding the sword of criticism, and raising the shield of self-justification.
The world needs more cross bearers and towel servants.
That is precisely what Jesus taught and modeled. It is his plan to bring his kingdom where needs are provided for, sinners are forgiven, and humans live in grateful peace.
