With Either Hand God's own best will bide the test, And God's own worst will fall; But, best or worst or last or first, He ordereth it all. For all is good, if understood, (Ah, could we understand!) And right and ill are tools of skill Held in His either hand. The harlot and the anchorite, The martyr and the rake, Deftly He fashions each aright, Its vital part to take. Wisdom He makes to guide the sap Where the high blossoms be; And Lust to kill the weaker branch. And Drink to trim the tree. And Holiness that so the bole Be solid at the core; And Plague and Fever, that the whole Be changing evermore. He strews the microbes in the lung, The blood-clot in the brain; With test and test He picks the best, Then tests them once again. He tests the body and the mind, He rings them o'er and o'er; And if they crack, He throws them back, And fashions them once more. He chokes the infant throat with slime, He sets the ferment free; He builds the tiny tube of lime That blocks the artery. He lets the youthful dreamer store Great projects in his brain, Until he drops the fungus spore That smears them out again. He stores the milk that feeds the babe, He dulls the tortured nerve; He gives a hundred joys of sense Where few or none might serve. And still He trains the branch of good Where the high blossoms be, And wieldeth still the shears of ill To prune and prune His tree. So read I this - and as I try To write it clear again, I feel a second finger lie Above mine on the pen. Dim are these peering eyes of mine, And dark what I have seen; But be I wrong, the wrong is Thine, Else had it never been. Sir Arthur Conan Doyle [As printed in "The Stark Munro Letters"]
