Coming from a Christian point of view, first of all, obligation isn't exactly the right word to use. As any parent has the obligation to feed their children, a loving parent won't see it as an obligation or burden. They feed their children because they love them. This is the same when you are a Christian. To be a Christian, followers must acknowledge and believe that God is the one and only God and that he sent his son Jesus to die on Earth so that we could have a relationship with God free of other religious obligations like sacrifices. Also a Christian should change their habits, actions, behaviours and attitudes so they align with God and his will. A Christian will do this because they love God and therefore don't see them as obligations.
