Romans 8:5-9 (NKJV)
There is a principle in life: What you feed grows. This principle works not only in the natural world but also in the spiritual. We are created with a body and a spirit. What we feed our physical body nourishes us. When we eat healthy food we reap healthy bodies. When we eat junk food and our bodies pay the price.
The same is true when it comes to our spirit-person. What you feed grows. Paul, in his epistles, writes a lot about the difference between living in the spirit and living in the flesh. Our spirit person either prospers or perishes depending on what we feed ourselves spiritually speaking.
What is your spirit feeding on: the things of God or the things of this world? What do you listen to on the radio? What do you watch on TV? What do you read? What do you search for on the internet? What do you think about? What can’t you get enough of? Are these things feeding your flesh or your spirit? What’s growing? What’s dying? Our spirits are healthy when we feed on the Word of God, when we pray, when we worship, when we set our minds on things above. (Colossians 3:1-3)
