We are truly saddened to hear about the struggles you are facing in your relationship. First, we must address that the Bible teaches us to flee from all forms of witchcraft and sorcery, as it is an abomination to God. As it says in Galatians 5:20 WEB, "idolatry, sorcery, enmities, strife, jealousies, outbursts of anger, rivalries, divisions, heresies."
However, we must also address that the Bible teaches us that we are to be united with fellow believers in marriage, not simply in a relationship. As it says in 2 Corinthians 6:14 WEB, "Don't be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what fellowship has light with darkness?" If you are not married, we encourage you to consider God's plan for marriage and to seek His will for your relationship. We are concerned that you mention your love is strong but did not mention Jesus Christ in your request.
The strife and arguments you are experiencing may not be a result of witchcraft, but rather an indication that you are not both in Christ Jesus. Psalm 127:1 says Unless Yahweh builds the house, they who build it labor in vain.
In addition, we must remind you that God does not support divorce except in cases of adultery or abandonment by an unbelieving spouse. As it says in Malachi 2:16 WEB, "For I hate divorce," says Yahweh, the God of Israel.
Instead of focusing on the supposed witchcraft, we encourage you to focus on your own relationship with God and to seek His will for your life. Pray for your relationship to be centered on God's will, His word, and a forgiven heart. As it says in Mark 11:25 WEB, "When you stand praying, forgive, if you have anything against anyone; so that your Father, who is in heaven, may also forgive you your transgressions."
Heavenly Father, we come before you in the name of Jesus Christ and we lift up ### and their courtship to you. We pray that you would reveal any areas of sin in their lives and that you would draw them both closer to you. We pray that you would give them wisdom and discernment as they navigate this difficult situation, and that you would protect them from any spiritual warfare that may be taking place. We pray that your will be done in their relationship, and that you would guide them. We pray for forgiveness in their lives and that they can extend it to others. We pray that you would heal any brokenness and restore any damage that has been done. We ask this all in Jesus' name. Amen.
We encourage you to pray together, and to seek God's will for your relationship. Put on the whole armor of God, and stand firm against the schemes of the devil as it says in Ephesians 6:11. Trust in God, and he will guide you to righteousness and peace.
