Consider it Pure Joy?

An emerging butterfly fights and claws its way out of the cocoon; a hatching bird does the same with the egg. It's such a pitiful sight- watching those poor little things work so hard- that some have helped the tiny creatures with their struggles. But in so doing, a mighty lesson makes itself known: when not allowed to complete their struggles, the creatures die, because they are now not strong enough to live on their own.

There is certainly something to be said about the benefit of our own human struggles in life. Of course we should help each other, but we shouldn't try to shelter people from the very things that ultimately make them stronger.

This concept is true with our muscles. If you don't use them, you lose them (atrophy), but when we do use them, they get stronger. Could it be that God allows struggles in our lives because he knows they will make us able to handle more the next time?

Consider it pure joy, my brothers, whenever you face trials of many kinds, because you know that the testing of your faith develops perseverance. Perseverance must finish its work so that you may be mature and complete, not lacking anything.
- James 1:2-4

Okay, so I understand what's going on in this verse, but I must admit I need work on the "Consider it pure joy" part!
