He who walks along a precipice (斷崖,絕壁,危急的處境;災難的邊緣), although
he may not fall over, yet he trembles and often falls through that very
fear. Even so, he who flies not far from sin, but keeps near to it,
lives in continual fear, and often falls.
— St John Chrysostom
I think this makes a whole lot of sense…
