Hey friend,

Let’s talk about something tender but deeply needed: sex, shame, and what Scripture actually says about our bodies and desires.

I remember being a kid, watching a movie with my family when a kissing or bedroom scene came on. Suddenly, chaos: Mom’s hands over my eyes, Dad scrambling for the remote, and my sisters yelling “Ew!” At the time, I was more confused than convicted. Was something bad happening?

Turns out, my parents were trying to protect me from cultural messages that say, “Sex is no big deal. Just do what feels right.”

But Scripture tells a different story—one that honors the sacred design of our bodies and the beauty (and power) of sexual intimacy. In 1 Corinthians 6:12-20, the apostle Paul confronts a cultural climate that isn’t so different from ours. And his message? Our bodies matter. Our choices matter. And we weren’t made to carry this alone.

12 “Everything is permissible for me,” but not everything is beneficial. “Everything is permissible for me,” but I will not be mastered by anything. 13 “Food is for the stomach and the stomach for food,” and God will do away with both of them. However, the body is not for sexual immorality but for the Lord, and the Lord for the body. 14 God raised up the Lord and will also raise us up by his power. 15 Don’t you know that your bodies are a part of Christ’s body? So should I take a part of Christ’s body and make it part of a prostitute? Absolutely not! 16 Don’t you know that anyone joined to a prostitute is one body with her? For Scripture says, The two will become one flesh. 17 But anyone joined to the Lord is one spirit with him. 18 Flee sexual immorality! Every other sin a person commits is outside the body, but the person who is sexually immoral sins against his own body. 19 Don’t you know that your body is a temple of the Holy Spirit who is in you, whom you have from God? You are not your own, 20 for you were bought at a price. So glorify God with your body.

1 Corinthians 6:12-20

Freedom That Heals, Not Harms

Paul starts by addressing a Corinthian mantra: “Everything is permissible for me.”

Yes, in Christ we are free. But Paul gently reminds us: not everything is beneficial. Freedom without wisdom can lead to bondage. Especially when it comes to our sexuality.

Sex, Paul says, isn’t just about appetite. It’s deeply spiritual. Our bodies aren’t just shells—they’re temples. They’re part of Christ. And when we misuse them, especially in the realm of sexual intimacy, it affects not just us but the entire body of Christ.

That’s a big deal.

Why Sexual Sin Feels So Personal

Paul zeroes in on sexual immorality because of its unique impact.

“Flee from sexual immorality,” he urges, “because every other sin is outside the body, but sexual sin is against one’s own body.”

Translation? Sexual sin sticks. It imprints on our nervous system. It messes with our sense of worth, connection, even our ability to feel safe in our own skin.

NICC (Neuroscience Informed Christian Counseling®) explains why: our brains are wired to bond through sex. Even casual encounters create deep emotional and physiological ties. That’s why breakups hurt. That’s why porn rewires our brain. That’s why “just sex” never really is.

But here’s the good news: the same God who wired your brain for connection also designed it for healing.

When You Feel Stuck in Shame or Addiction

Maybe you’re reading this and thinking, “I’ve already blown it.”

Friend, hear this: You are not beyond grace. You’re not damaged goods. You are deeply loved.

Paul’s words aren’t meant to shame us—they’re meant to set us free. Because we were bought at a price. Jesus didn’t just save your soul—He redeemed your whole body. Your sexuality included.

But walking that out? It’s hard. Especially if you’re stuck in cycles of porn, hookups, emotional dependency, or shame. These aren’t just “bad choices” — they’re often survival strategies from an overwhelmed nervous system trying to cope.

That’s where Christian counseling comes in.

The Role of Counseling in Sexual Healing

At MyCounselor.Online, our NICC-trained Christian therapists understand both the spiritual weight and the neurological impact of sexual immorality. They won’t shame you. They’ll walk with you.

NICC sees sexual sin not just as a moral failure, but often as a sign of deeper wounds, unmet needs, or unprocessed pain. Through safe, Spirit-led sessions, we help you:

  • Heal from past sexual trauma or betrayal
  • Break free from porn and sexual addiction
  • Reconnect with your true identity in Christ
  • Rewire your brain for joy, peace, and secure love

We believe healing isn’t just possible—it’s promised. Jesus meets us in the mess, not after we’ve cleaned it up.

Final Thoughts

So, why flee sexual immorality? Not because God wants to steal your fun. Because He wants to restore your freedom.

You were made for sacred connection. Your body is not disposable. Your story is not over. And you don’t have to navigate this alone.

If this stirred something in you—a longing, a regret, a flicker of hope—we’d love to walk with you.

Reach out to one of our NICC therapists. Let’s begin the journey from shame to freedom, from Fake Joy to the True Happiness your soul is craving.

We’re cheering you on.

You are not your past. You are God’s beloved.

And your healing starts here. Get Started Today
