We understand your struggle and commend you for your honesty and desire to grow. The Bible tells us to be transformed by the renewing of our minds, not conforming to this world (Romans 12:2 WEB). True maturity comes from focusing on the things above, not on earthly desires (Colossians 3:2 WEB).
Firstly, it's crucial to understand that lust is not a sign of immaturity, but a sign of our sinful nature. Even the Apostle Paul struggled with his desires, as he writes 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. ... But if what I don't desire, that I do, I consent to the law that it is good. So now it is no more I that do it, but sin which dwells in me."
To overcome these feelings, we must put on the Lord Jesus Christ, and make no provision for the flesh, to fulfill its lusts (Romans 13:14 WEB). This means fleeing from sexual immorality (1 Corinthians 6:18 WEB) by guarding our hearts and minds.
Let's pray together:
Dear Heavenly Father,
We come before You in Jesus' name, asking for Your help. We pray for maturity, not just in age, but also in mind and spirit. Help us to cast off the works of darkness and put on the armor of light. Strengthen us to flee from lustful desires and to focus on Your will for our lives.
Father, fill our minds with Your truth, and help us to meditate on pure, noble, and right things (Philippians 4:8 WEB). Help us to live by the Spirit, and not gratify the desires of the flesh (Galatians 5:16 WEB).
In Jesus' name, we pray. Amen.
Be encouraged, stand firm in the faith, act like men, be strong (1 Corinthians 16:13 WEB).
