This is something I've been thinking a lot about lately, how we don't like to give our lives to God, but we'll emphasize sacrifices. I will go to church and give a little money, but don't ask me to be be godly at work, that's a little much.
At one point Jesus was talking with a religious leader and talked about the greatest commandment (love God with all your heart, soul, mind and strength). People like that, it sounds nice, but what does that mean? I like how the teacher responded:
Mark 12:33 ~ "One must love God with all his heart, all his mind, and all his strength. And one must love his neighbor as he loves himself. These commands are more important than all the animals and sacrifices we offer to God.” (NCV)
It's more important to live a life that is godly than to give God the "requirements" of Sunday morning. What if we all lived like that? After all, Jesus' answer to this statement: “You are not far from the Kingdom of God.” (Mark 12:34). That's how you get to heaven, or better yet, bring heaven to people here on earth.
