This phrase sounds very familiar to me, but I know I've never seen the hymn before; maybe Chesterton uses the phrase somewhere in his prose?
In any case, especially timely.
Hymn for the Church Militant
Great God, that bowest sky and star,
Bow down our towering thoughts to thee,
And grant us in a faltering war
The firm feet of humility.Lord, we that snatch the swords of flame,
Lord, we that cry about Thy ear,
We too are weak with pride and shame,
We too are as our foemen are.Yea, we are mad as they are mad,
Yea, we are blind as they are blind,
Yea, we are very sick and sad
Who bring good news to all mankind.The dreadful joy Thy Son has sent
Is heavier than any care;
We find, as Cain his punishment,
Our pardon more than we can bear.Lord, when we cry Thee far and near
And thunder through all lands unknown
The gospel into every ear,
Lord, let us not forget our own.Cleanse us from ire of creed or class,
The anger of the idle kings;
Sow in our souls, like living grass,
The laughter of all lowly things.
