1 Corinthians 15:55-58
O death, where is your sting? O grave, where is your victory?…
Whilst the stream keeps running it keeps clear; but if it comes once to a standing water, then it breeds frogs and toads and all manner of filth. The keys that men keep in their pockets, and use every day, wax brighter and brighter; but if they be laid aside and hang by the walls, they soon grow rusty. Thus it is said that action is the very life of the soul. "Always abounding in the work of the Lord" is the way to keep clear and free from the pollutions of the world.
