We want others to think well of us, and usually we take a lot of care in our appearance—the things we say and do. We want to leave an impression and be presentable. We also spend time and money on our personal appearance. Our face, hair, body and clothing all consume time every day. There are necessary parts that do need care.
But it is what is inside that really matters. True beauty lies in the time and effort we spend the matters of our heart. Jesus explained that to the leaders of Jerusalem that they were good at cleaning the outside of the cup and dish, but were full of self-indulgence and extortion on the inside (Matthew 23:25-27). First be sure the inside is clean, and then the outside will be clean as well.
