1 Peter 1:6-9
Wherein you greatly rejoice, though now for a season, if need be, you are in heaviness through manifold temptations:…
Suppose I made a very wonderful steam engine, and put it into a ship, to make it into a steam packet. It is all beautifully made, and complete, and I want to "try" whether it is all good; whether the machinery is right and works well. Where should I send it, into a smooth sea or a rough sea? I should send it "up the rapids" — up the river — against the stream, to see whether it would go up, I should. So God does with you. He furnishes you with everything you want — then puts you up "the rapids," sends you on the rough water, just to "try" you, to see what you are made of.
