We are truly sorry to hear about the struggle with alcohol addiction and the pain it has caused. We commend you for your humility and honesty in acknowledging your situation and seeking God's help. It is only by the name of Jesus that we have access to God. Your request is only possible because of the salvation that Jesus offers. It is only by confessing with our mouths that Jesus is Lord and believing in our hearts that God raised him from the dead that we are saved.
Firstly, let us address the spiritual warfare aspect you mentioned. When we give in to sin, it's true that we can open doors to spiritual bondage. You referred to the scripture about the unclean spirit returning with seven other spirits more wicked than itself (Matthew 12:43-45 WEB). This emphasizes the importance of staying vigilant and filled with the Holy Spirit.
Jesus said, "If therefore the Son makes you free, you will be free indeed." (John 8:36 WEB) Freedom from addiction is possible through Jesus Christ. Remember, "God is faithful, who will not allow you to be tempted above what you are able, but will with the temptation also make the way of escape, that you may be able to endure it." (1 Corinthians 10:13 WEB)
Let us pray together:
Dear Heavenly Father,
We come before you in the name of Jesus, lifting up our brother/sister in their struggle with alcohol addiction. Lord, they have humbly come to you, acknowledging their sin and seeking your mercy and deliverance.
We pray, Lord, that you break the chains of addiction in their life. Cast out any evil spirits that may have taken hold, and fill them anew with your Holy Spirit. Give them strength and wisdom to resist temptation and the courage to make the changes needed in their life.
Surround them with supportive believers who will encourage and help them in their journey to sobriety. Restore their joy and peace, and use their testimony to help others who may be struggling with similar issues.
In Jesus' name, we pray. Amen.
Moving forward, it's crucial to engage with a community of believers who can support and encourage you. Seek accountability partners and consider professional help for your addiction. Remember, God's will is for you to be free indeed.
Also, meditate on the following scriptures:
"Be sober and self-controlled. Be watchful. Your adversary the devil, walks around like a roaring lion, seeking whom he may devour." (1 Peter 5:8 WEB)
"Put on the full armor of God, so that you can stand against the devil's schemes." (Ephesians 6:11 WEB)
"Don't be drunken with wine, in which is dissipation, but be filled with the Spirit." (Ephesians 5:18 WEB)
Stay strong in the Lord. We are here with you in spirit, praying and believing for your complete deliverance and restoration.
