We understand your concern and are here to support you in prayer and truth. Firstly, it's important to address that the power of evil spirits and witchcraft is very real, but as believers in Jesus Christ, we have authority over them. As it is written in Luke 10:19, "Behold, I give you authority to tread on serpents and scorpions, and over all the power of the enemy, and nothing will in any way hurt you."
However, we must also address that the Bible is clear about being unequally yoked. As 2 Corinthians 6:14 says, "Don't be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what fellowship has light with darkness?" As believers, we should not be in a relationship that does not align with biblical principles.
We believe in the sanctity of marriage between a man and a woman, and relationships should be a courtship with the goal of marrying another Christian believer. Living together, dating just for fun, and having a relationship with a girlfriend are all outside of biblical principles. It is the same with any relationship with a girlfriend as it is a form of a boyfriend girlfriend relationship. You should be looking for a wife, and she should be looking for a husband. If she is not looking for a husband, then you should look for a Christian woman who is. God will provide someone who is a Christian, and who wants to be married to another Christian. God will provide someone who also wants to obey God and be in agreement with God's word.
Additionally, we are concerned that your request does not mention the name of Jesus Christ. It is only by the name of Jesus that we have access to God. As it is written in John 14:6, "Jesus said to him, I am the way, the truth, and the life. No one comes to the Father, except through me." We encourage you to put your faith in Jesus Christ if you have not already done so.
In response to your request, we pray:
Heavenly Father, we come before you in the name of Jesus Christ, acknowledging that there is power in witchcraft, but we also know that you are the one true God and the giver of life and salvation. We pray for this situation, asking that you would bring and end to all witchcraft, spells, or curses that are being practiced against them, and that you would provide protection and spiritual guidance.
We also pray that you would give this individual wisdom and clarity in their relationship, and that you would guide them to be in a relationship with a Christian who is looking for a wife. We ask that you would give them the strength to end any relationship that is outside of your will, and that you would bring them a spouse that honors and serves you.
We pray for the mother and the girlfriend that they would come to repentance and turn to you, Jesus, and that you would have mercy on their souls.
In Jesus' name, we pray. Amen.
