If you were a dog, would your tail be wagging today? If you are happy on the inside, it will show on the outside. Proverbs 15:13 says, "A joyful heart makes a cheerful face." If you have anger on your face, it's because you have anger in your heart. And if you have a big smile on your face, it's because you have joy in your heart.
Jesus said, "These things I have spoken to you so that My joy may be in you, and that your joy may be full" (John 15:11). The best advertisement for Jesus Christ is a joyful Christian. It has been said that 18th century evangelist George Whitfield had so much joy that people wanted to be saved just by seeing the joy on his face. Do you have that kind of joy?
