surrender and praise

During my devotion today, it got me thinking to why we live the way we do. Why push away lust? Why sacrifice our time and money for others who sometimes don't deserve it? Why do we live our lives so differently from the world? The simple answer is because it pleases God but is that the real reason we act the way we do? Do we only do good in the eyes of others but when we're all alone and there's no one there to see us sin and disobey God, do we act differently? I sure hope not. The person we are at church should be the person we are wherever we go. We need to FULLY surrender our lives to God and not just fool people to think that we are.
