The Bible never gives a precise list of physical boundaries for dating, but it consistently teaches that sexual intimacy belongs within the covenant of marriage and should be treated as holy (Genesis 2:24; Leviticus 19:2). Rather than asking, "How far can I go?" Scripture calls believers to pursue wisdom by avoiding situations that fuel temptation and awaken desires that cannot be righteously fulfilled outside of marriage (Proverbs 6:27–28; Song of Solomon 2:7). Purity, however, is not just about actions but involves both our behavior and our desires (Matthew 5:27–28). We are not to flirt with sexual sin but to abstain from it and to flee from it altogether (1 Thessalonians 4:3–5; 1 Corinthians 6:18). Biblical love is not driven by personal gratification but by a desire to honor God and seek another person's spiritual good (1 Corinthians 13:5). Because of this, the question is not where the line is and how close is too close but whether your relationship is helping both of you grow closer to Christ and guarding each other's purity. If physical intimacy is stirring up desires reserved for marriage, weakening self-control, or moving you toward sexual sin, then you've already crossed into territory Scripture warns against (Galatians 5:22–23; Song of Solomon 8:4).
Can we hold hands? Kiss? Make out? Take a nap together? Those questions aren't ultimately answered by asking, "Where is the line?" and "How close is too close?" but by asking, "Am I loving this person I am dating the way Christ calls me to?"
The danger in dating is that we often focus on avoiding the final step of having sex while ignoring all the smaller steps that awaken desires we were never meant to satisfy outside of marriage. And when we do so, we inch closer and closer and become more and more numb to what we allow. "Well, we've already done this, so what's the harm in going further?" When you continually push physical boundaries, you're not just risking temptation; you're practicing a pattern of taking rather than serving, consuming rather than protecting, and indulging rather than exercising self-control.
In doing this, you are stealing something from your future spouse. If the person you're dating is not your future spouse, you're giving away forms of intimacy that should lead to and only belong within a future marriage covenant. And even if that person does become your spouse, you are still robbing both of you of something important: the opportunity to learn how to love sacrificially and exercise self-control before marriage.
Self-control is not a skill that suddenly appears on your wedding day. The habits you build while dating are often the habits you carry into marriage. If you train yourself to constantly push boundaries now, don't be surprised when you struggle to honor boundaries later. Real love while dating doesn't ask, "How much can I get away with?" It asks, "How can I honor God and protect this person's heart, purity, and future?" Sometimes the most loving thing you can do for someone is not to get as close as you can, but to willingly choose restraint because their holiness matters more to you than your desires.
