How does God's design for sex impact a Christian's view of consent?

from the old testament

• Consent is the willing, informed, and voluntary agreement of a person to participate in something. In the context of sex, consent refers to both people willingly and freely agreeing to sexual activity without coercion, manipulation, pressure, fear, or deception.
  Consent is good in that it recognizes that people are not objects to be used but image-bearers of God who have dignity, agency, and worth (Genesis 1:26–27). However, consent is not the foundation of sexual ethics; God’s design for sex is.
• Sex is designed by God to exist within the covenant of marriage, where a husband and wife give themselves fully to one another (Genesis 2:24; see also Ephesians 5:25–33). There are parameters around marriage and sex because God’s design protects the dignity of people and preserves the goodness of His gift.
  
• The Old Testament condemns sexual exploitation, coercion, and using others for selfish desire. Laws concerning sexual assault (Deuteronomy 22:25–27) show that God takes violations of a person’s will and dignity seriously. These laws reveal that God does not view people as objects whose bodies can be taken or controlled by someone else.
  
• Love seeks the good of the other person, not merely personal gratification. Song of Solomon portrays marital intimacy as mutual, joyful, and honoring. Both husband and wife express desire and delight in one another (Song of Solomon 4:9–10; 7:10–13). Sexual intimacy in God’s design involves mutual affection, trust, and commitment.  In contrast, when sexual desire becomes focused on taking rather than loving and not following God's design, it is a sin and leads to all sorts of negative consequences. For example, Amnon’s abuse of Tamar shows the destructive nature of selfish sexual desire (2 Samuel 13:1–19). Amnon became consumed by his desire for Tamar, deceived her, and forced himself on her, treating her as an object to satisfy his own urges rather than as a person worthy of honor and care. His actions reveal the opposite of biblical love, which seeks the good of the other person and values their dignity.
  
• God’s design for sex means consent cannot be reduced to “both people wanted it.” The biblical question is not only whether someone agreed but whether the relationship reflects God’s purposes: covenant faithfulness, love, holiness, and honor.

from the new testament

• The New Testament continues the principle that sexual intimacy belongs within marriage, where love is expressed through self-giving commitment. Jesus affirmed God’s design for marriage from creation (Matthew 19:4–6). Hebrews 13:4 says marriage should be honored and the marriage bed kept pure. The New Testament challenges a cultural view of consent that focuses only on personal autonomy. Culture often defines sexual morality primarily by whether two people agree, suggesting that anything consensual is automatically good. But the Bible teaches that consent alone does not determine what is morally right; God’s design, holiness, love, and faithfulness also matter.
  
• Jesus taught that people must be valued as persons, not used as objects for selfish desires. Jesus summarized God’s commands as loving God and loving others (Matthew 22:37–39). Any sexual relationship that disregards another person’s dignity, well-being, or holiness contradicts this command.
  
• Paul teaches that husbands and wives should give themselves to one another in mutual love and care (1 Corinthians 7:3–5). This mutuality shows that sex is not about taking what one desires but about lovingly considering and serving the other person. Though this follows the principle of consent, it is more than that, and it has God's design of sex as the foundation.
  
• The New Testament rejects sexual immorality because it separates sex from God’s intended purpose. Paul warns against sexual immorality because the body belongs to the Lord (1 Corinthians 6:18–20). Christians are called to honor God with their bodies rather than allowing desire to become their master.
• Love involves seeking another person’s good, not merely satisfying personal desires. Love is patient, kind, and does not insist on its own way (1 Corinthians 13:4–5). Philippians 2:3–4 calls believers to look not only to their own interests but also to the interests of others.

implications for today

God’s design for sex transforms the Christian understanding of consent. Consent is not merely “permission to access someone’s body”; it is part of a larger commitment to honor someone as an image-bearer of God. In a culture that often defines sexual ethics by one question—“Did both people agree?”—Christians are called to ask a deeper question: “Does this reflect God’s love, holiness, and purpose for people?” God’s design reminds us that another person is never a means to satisfy our desires but someone created with dignity, value, and worth. The gift of sex is meant to be enjoyed when a man and a woman, understanding each person's value, commit themselves to one another for life in the covenant of marriage. It is there that sex can be a blessing, within commitment and a loving relationship.

So, when culture talks about sex as if it is a right, entitlement, or expectation, it fails to factor in the truth that sex will not ultimately satisfy if we do not follow God's design for it. Consent cannot be the driving factor to determine if a couple is "ready to have sex." A couple may mutually desire something and still be outside of God’s design for it. Biblical wisdom asks more than whether something is wanted; it asks whether it is good, honoring, and aligned with God's purpose, knowing that anything outside of it hurts God, us, and others. True love is not measured by how much someone can receive from another person but by how faithfully they can love, honor, and give themselves for the good of the other.

This means Christians are called to approach sexuality with a different mindset than the world. Instead of asking, “How far can we go?” or “Do we have permission?” the better question is, “How can we honor God and protect the dignity of the person He has allowed us to be in relationship with?”

God’s boundaries are not meant to restrict love but to preserve its beauty. When sex is placed within God’s design, it becomes more than a moment of mutual desire; it allows love to flourish.
