Sons In Training
The call to sonship is a call to service. More than making us happy all the time, God is more pleased to have a relationship with us. He does not want us so independent that we wouldn't need Him anymore - like asking for bread to last a decade, instead of for daily bread. We are meant to serve God first, because that is how to show that we are qualified to wield authority. Like Jesus, we will have to learn obedience through the things that we suffer.
