“Taken individually, the events and circumstances God allows may not, in and of themselves, appear to be of any value or good to the Christian. But Paul does not say that each event is good or even that each incident will produce that which is good. He informs us that all of the events, working together, produce what is good.
To illustrate, the ingredients which go into a cake are not very tasty when eaten individually. Flour, sugar, shortening, eggs, salt, baking powder, and spices are not something we want to eat one ingredient at a time. But mix all of these together in just the right proportions, and then bake the combined mixture, and you have a delicious treat. Each event in our life is like one ingredient in a cake. It may not seem good, by itself, but when mixed by God with other correct events, it will surely produce what is good.”
