We understand the struggle you're facing and we want you to know that you're not alone. The apostle Paul also struggled with sin, as he wrote in Romans 7:15-20 (WEB): "For I don’t know what I am doing. For I don’t practice what I desire to do; but what I hate, that I do. ... For the good which I desire, I don’t do; but the evil which I don’t desire, that I practice. ... but sin that dwells in me, that when I want to do good, evil is present with me. For I delight in God’s law after the inward man, but I see a different law in my members, warring against the law of my mind, and bringing me into captivity under the law of sin which is in my members."
First, let's address that the act you're struggling with is indeed a sin. It's important to call it what it is because that's the first step in overcoming it. 1 Corinthians 6:18 (WEB) says, "Flee sexual immorality! 'Every sin that a man does is outside the body,' but he who commits sexual immorality sins against his own body."
But there is hope and forgiveness in Jesus Christ. As Romans 7:24-25 (WEB) continues, "What a wretched man I am! Who will deliver me out of the body of this death? I thank God through Jesus Christ, our Lord!"
Let's pray together:
"Dear Heavenly Father, we come before you in the name of Jesus, lifting up this young believer struggling with sin. Lord, he knows his actions are wrong and wants to stop. We ask for your forgiveness and your strength to help him overcome this temptation. Lord Jesus, you were tempted in every way, just as we are—yet he did not sin. Help him to stand firm in your power and not his own. In Jesus' name, we pray. Amen."
We encourage you to stay in God's Word, memorize scriptures that combat this temptation, and pray continually. Also, consider confiding in a trusted Christian adult or mentor who can provide guidance and accountability. Remember, God is faithful, and he will make a way to escape temptation (1 Corinthians 10:13). Keep fighting the good fight of faith, and remember that your identity is in Christ, not in your struggles.
Lastly, we noticed that you didn't mention the name of Jesus in your request. It's important to remember that it is only through Jesus that we have access to God. As Acts 4:12 (WEB) says, "There is salvation in no one else, for there is no other name under heaven that is given among men, by which we must be saved!"
