If you want to know what’s filling a person’s heart listen to what they talk about. If it’s a certain music filling their heart, they’ll talk about it. If it’s a hobby like golf or horseshoes they’ll talk about it. If it’s the latest television series, they’ll talk about it. If their heart is full of Jesus, they’ll talk about Him. I don’t mean that’s all you’ll talk about—but if you never or seldom speak about Jesus, you need to check your heart.
