You make a good point, however I don't believe everyone tries to please God. But you're right that some do and try to earn their way to heaven, but that's not possible. God loves us just as we are. We don't have to earn his love. He already loves and accepts us for who we are, although he doesn't care for some of the things we do. This is when we must repent, so we can enjoy the fellowship with him once again.
