How can I stop masturbating?

from the old testament

• God puts boundaries around our sexual activity, confining it to marriage of one man and one woman (Genesis 2:24). Any sexual activity outside of that is sin.
• Masturbation reveals the desire to seek comfort apart from God's design for sex. As with many sins, the answer is turning to God and praying for His intervention as David did: "Create in me a clean heart, O God, and renew a right spirit within me" (Psalm 51:10).

from the new testament

• Masturbation is sinful because it separates sexual desire and pleasure from God’s design for sex, which He created to be expressed between a man and a woman within the covenant relationship of marriage. The New Testament affirms that sexual intimacy belongs within the marriage covenant alone (Hebrews 13:4).
• Sexual sin, including masturbation, is often encouraged or exacerbated by  unwholesome content—e.g., unwholesome movies and books, pornography. Believers should not allow such content into their lives. The apostle Paul wrote to the Philippians about what we should fill our lives with: ". . . whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things" (Philippians 4:8). When we consume only what is beneficial to our Christian walk, our thought life changes.
• No sin, including sexual sin like masturbation, is too powerful for God. God has promised not to allow anything into His children's lives that will tempt us more than we can bear: "No temptation has overtaken you that is not common to man. God is faithful, and he will not let you be tempted beyond your ability, but with the temptation he will also provide the way of escape, that you may be able to endure it" (1 Corinthians 10:13).
• The resources God has given us helps us to resist sin: Scripture (2 Timothy 3:16-17), prayer (Matthew 6:13), and support of other believers (Hebrews 10:25; Galatians 6:2). When we take advantage of these spiritual resources, we are "walk[ing] by the Spirit"  and by doing so, "will not gratify the desires of the flesh" (Galatians 5:16).
• Those who are tempted to masturbate should remember that a believer's body is the temple of the Holy Spirit and should be used for honorable purposes. Paul told the Corinthians, "glorify God in your body" (1 Corinthians 6:19–20).
• Falling into sexual sin should not lead believers to give up and then give in to more sin. God has promised "If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness" (1 John 1:9).

implications for today

"What people do in the privacy of their own homes is their business."

"As long as you're not hurting anybody, do what you want."

Those slogans sound freeing, but they fall apart under closer examination. Sin is never harmless. It damages our relationship with God, distorts His image in us, and often shapes the way we view ourselves and others. Because God created us, He alone defines what is good, including His design for sex as the lifelong covenant between one man and one woman in marriage. Masturbation takes God's good gift of sexuality and redirects it inward, separating sexual pleasure from the covenant relationship for which it was created.

The good news is that temptation does not have to define you. In a world filled with constant sexual temptation through phones, social media, entertainment, and countless other distractions, God has not left you to fight alone. He has given you His Spirit, His Word, prayer, and the support of His people to help you pursue purity. You can choose to stop fueling what leads you to sin. You can seek accountability to keep you from giving into sexual temptation. You can remember God's promises to satisfy you.

Freedom is usually built through small, faithful choices. Remove sources of temptation, fill your mind with what is true and pure, turn to God before temptation becomes overwhelming, and invite a trusted believer to encourage and hold you accountable. These practices help you walk in the strength He provides.

And when you fail, don't let shame keep you from the One who can restore you. Confess your sin, receive God's forgiveness, and keep pursuing holiness. Jesus didn't die merely to forgive your past failures; He died to transform you into someone who increasingly reflects His purity, self-control, and love.
