God says don't settle for a D

I was watching a Pastor on TV part of his sermon today was about how we settle for things. He says God does not want us to settle for a D meaning we should push for a A. Don't let your thoughts say you can't do better. If you are not happy with a relationship try to do better, If you are not doing good in school do better, If you are not doing good financially don't settle for nothing push yourself for a better life. If you don't have Faith read the word more. If you think you should have a relationship with your grandchild don't settle for not seeing or being apart, Do your best to get a A. your life will change if you put your all into what you love. With God all things are possible!
