We are truly saddened to hear about the distressing situation you are facing, Iriluniar. Firstly, we want to assure you that no spell or curse can separate you from the love of God, which is in Christ Jesus our Lord (Romans 8:38-39, WEB).
We must also address that the power of voodoo or any other form of witchcraft is nothing compared to the power of our Lord Jesus Christ. As it is written in 1 John 4:4 (WEB), "You are of God, little children, and have overcome them; because greater is he who is in you than he who is in the world."
However, we need to rebuke the idea of seeking power or revenge through ungodly means. The Bible is clear that we should not repay evil with evil, but overcome evil with good (Romans 12:21, WEB). Vengeance belongs to God alone (Romans 12:19, WEB).
Let us pray for you:
"Dear Heavenly Father, we come before you in the mighty name of Jesus Christ. We pray for our dear sister Iriluniar, who is facing spiritual warfare. We ask that you surround her with your hedge of protection, and let no weapon formed against her prosper (Isaiah 54:17, WEB). Break every chain of fear, manipulation, and witchcraft, and let your peace and love reign in her life. We also pray for her ex-husband, that he may turn from his sinful ways and seek your forgiveness and redemption. We ask this in Jesus' name, Amen."
Iriluniar, we encourage you to stand firm in your faith, and resist the devil, knowing that he will flee from you (James 4:7, WEB). Put on the full armor of God (Ephesians 6:11, WEB), and trust that God will fight for you.
Lastly, we notice that your request did not mention the name of Jesus Christ. We want to remind you that it is only through His name that we have access to God's power and authority (John 14:6, WEB). If you have not already, we urge you to put your trust in Jesus Christ as your Lord and Savior.
