You can feed your spirit man or you can feed your flesh. Which side wins in your life – your spirit or your flesh? Probably whichever one you feed more! If you want something to grow, feed it, and if you want something to wither away, starve it!
You get good at walking in the Spirit the same way you get good at walking in the flesh – practice! I got good on the piano because I practiced an hour a day (more toward the end) during 12 years of lessons. It was not an accident. And let me tell you, it was not always fun to practice! I threatened to quit more than once but my folks wouldn’t let me. But now it’s like second nature and I don’t have to think too hard about what I’m doing.
Walking in the Spirit is the same way; the more you practice, the better at it you get. I hit lots of wrong notes before I learned to hit the right ones when I learned new songs. You might hit some “wrong notes” yourself, but the only way you’ll ever hit the right notes is to keep working at it. The more you pray, the easier it gets. The more you read the Word, the easier it gets to read the Word without your head distracting you about all the things you need to get done.
But walking in the flesh is the same way, too. If you keep at it, you can get really good at it. It can become “second nature” so that walking in the Spirit seems abnormal and fleshing out seems normal. This is a tragedy for a Christian, to whom the flesh is legally crucified with Christ.
People who want to change their bodies often change their diet to get the desired results. Sometimes when we look at ourselves and don’t like where we are, we have to change our spiritual diets. We have a saying in the computer business, “Garbage in, garbage out.” Your head can be like that – if you put garbage in, you’ll get garbage out. But you can put the Word in and get the Word out instead! Make an effort to sow what you want to reap!
