Is God a Spoil Sport?

In Book 8 St. Augustine is attempting to decide whether to become a Christian. He wants to be a Christian but cannot find it in himself to give up his wordly pleasures. Is God being a spoil sport by making us give up our worldly pleasures to follow Jesus?

I don't think He is. One of St. Augustine's biggest problems is being chaste. God knows that St. Augustine will be happier when he gives up pre-marital sex. He is not trying to spoil St. Augustine's fun, but rather to protect him and give him a  better life. St. Augustine still doesn't understand that having a physical relationship with a woman without the long term committment of marriage is not going to bring him long term happiness. God knows this and in time St. Augustine will, too.
