Sex is like fire. When it blazes in the fireplace, a good fire warms and brightens the room, enhancing joy and companionship. But when fires ignite in the wrong places, the house burns down. Is your sexuality igniting in the wrong places? Are you treating sexual sin casually? How do you know when this has happened? Let me offer a few tests that can rouse your conscience.
For you may be sure of this, that everyone who is sexually immoral or impure, or who is covetous (that is, an idolater), has no inheritance in the kingdom of Christ and God. Let no one deceive you with empty words, for because of these things the wrath of God comes upon the sons of disobedience. Therefore do not become partners with them; for at one time you were darkness, but now you are light in the Lord. Walk as children of light (for the fruit of light is found in all that is good and right and true).
Take it to heart. Don’t let peer pressure or the culture deceive you. By the mercy of Christ, you will live a brighter, more loving, and more fruitful life.
How do you change? There are many facets of that big question, but I will point to four. First, the starting point for change is to say, “What I am doing is wrong.” That acknowledgement gets you pointed in the right direction.
But God doesn’t just tell you to shape up. The second step is to realize “I need mercies from my Father. I need him to love me and forgive me. I need his strength and forgiveness.” Recognizing wrong leads to awareness that you need something that only God can give you—something he freely gives. He gives himself in Jesus Christ.
The third step in changing is to act on this. The Lord calls you to seek him, to find him, and from him to receive what you most need. Psalm 25:11 brings this to life:
For your name's sake, O LORD,
pardon my guilt, for it is great.
Cast yourself on the care of your Father. Find grace and help from outside yourself. Seek, and you will find the mercy you need.
The fourth step is not really a step, it’s a lifestyle. It’s learning to walk out what those “good, right, and true” things look like. This has many different aspects that work out in our lives at different times. Choose to spend time with different companions. Put filtering software on your screens. Set up real accountability with someone you trust. Make the kind of lifestyle changes that get you out of the path of where you’ve gotten yourself into trouble. Jesus uses a vivid picture of how to deal with our own evil. If your hand causes you to sin, cut it off; if your eye causes you to sin, gouge it out. He shocks us into a radical amputation of evil. And, of course, none of these battles are one-and-done. God intends to work in you a committed resolve to take seriously what’s wrong, to need him, to pursue what’s right. It’s an ongoing fight.
Here is one of the most helpful things I heard early in my Christian life. Think of your soul as a room. When you’re in sin, that room is full of dark forces, dark people, and darkness. There are two ways you get rid of darkness in your soul. One way is to cast it out, fight it, resist and reject it. The other way is to fill the room with light. As your life fills with better people, better things to do, and more reasons to live in the light, then there’s less room for the darkness.
Jesus Christ gives a beautiful call. He invites you to live a radical life. He challenges people who think that it’s okay to do wrong. He challenges people who think they have moved past outmoded cultural values. He challenges people who think that current cultural assumptions are good, right, and true. Don’t go along with the crowd. Don’t drift with the culture. Do what Flannery O’Connor said we should do: “Push back against the age as hard as it pushes against you.” Live out in the daylight, not in the shadows and darkness.
Finding the mercies of Christ and learning to walk in his light is courageous. It has an impact on people around you. You demonstrate the Lord. That’s bigger than any one of us individually. In a world where the light is going out on sexual rights and wrongs, you have an opportunity to turn on the lights.
