We are truly saddened to hear about the distressing situation your girlfriend is facing. Firstly, we need to address that the request does not mention the name of Jesus Christ, Jesus, or Christ or an abbreviation such as IJN (In Jesus Name). It is only by the name of Jesus that we have access to God. The Bible is very clear that salvation comes through no other name, Acts 4:12 WEB Neither is there salvation in any other, for there is no other name under heaven that is given among men, by which we must be saved! Moreover, we are made holy by His name and we can rejoice in it:
1 John 3:23 WEB: This is his commandment, that we should believe in the name of his Son, Jesus Christ, and love one another, even as he commanded us.
If your girlfriend has not sought salvation in Jesus' name, we encourage her to do so, as it is the first step towards true peace and deliverance.
Now let us address your concerns.
We are also called to love one another and this includes doing good even to our enemies, Matthew 5:44 WEB But I tell you, love your enemies, bless those who curse you, do good to those who hate you, and pray for those who mistreat you and persecute you. This does not mean that we allow them to cause damage to ourselves or others but we should want the best for them, seeking their repentance and salvation. We should also seek that this person repents and finds forgiveness for their sins.
It is commendable that you are seeking help and not trying to handle this alone. God calls us to bear one another's burdens, Galatians 6:2 WEB: Bear one another's burdens, and so fulfill the law of Christ.
We will pray for this situation and for both you and your girlfriend. However, we want to remind you that God calls us to be holy and to flee from sexual immorality.
1 Corinthians 6:18 WEB: Flee sexual immorality! Every sin that a man does is outside the body, but he who commits sexual immorality sins against his own body.
If you and your girlfriend are involved in a romantic relationship, we encourage you to consider it a courtship with the goal of marriage. It is God's design that sexual intimacy be reserved for marriage between a man and a woman.
Now, let us pray together:
Almighty God, we come before You in the name of Jesus, lift this situation up to You. We pray for the man who is causing harm, that he would repent and seek forgiveness. We pray for your protection and comfort over the one who is being harmed. We pray that you would give them the strength to endure, and the wisdom to know how to handle this situation. We also pray for the one who submitted this request, that You would give them Your peace and guidance. If they are in a relationship that does not honor You, convict them and lead them into Your ways. We ask that you would guard their purity and help them to seek a godly spouse.
We ask these things in Jesus' name. Amen.
