We understand that you are seeking prayer and help for the woman you are in a relationship with, and we are here to intercede and provide biblical guidance. First, let us pray together:
Dear Heavenly Father, we come before you in the name of Jesus Christ, lifting up this relationship and the woman in question. We pray that you would deliver her from any lifestyle that does not honor you, including partying and entertaining different people in her home. We pray, Father, that you would give her a spirit of wisdom and revelation in the knowledge of you, and that the light of the Gospel would illuminate her heart (Ephesians 1:17-18). We pray for every evil spirit to be cast out and away from her and this relationship. We ask in the name of Jesus to see her grow in the grace and the knowledge of our Lord and Savior Jesus Christ. Amen (2 Peter 3:18).
Now, let us address this situation biblically. It is important to remember that God calls us to be holy and set apart for Him (1 Peter 1:16). If the woman you are in a relationship with is engaged in a lifestyle of partying and entertaining different people, it is not in line with God's will for her life or your relationship.
Moreover, it is crucial to remember that God calls us to be equally yoked in our relationships (2 Corinthians 6:14). This means that, as Christians, we should be seeking marriages and courtships with those who also know and love the Lord. If the woman you are involved with is not living a life that honors God, it is important to pray for her salvation and encourage her to live for Christ, but it is also important to consider whether this relationship is one that God wants for you.
We must love her with a Christian love as a neighbor. If she is a Christian, then she is our sister in Christ first and should be treated and approached as such.
Furthermore, if you have been involved in the same sinful lifestyle as this woman you are in a relationship with, it is important to acknowledge that this is also immoral. We must always examine our own lives first before confronting others (Matthew 7:3-5).
Lastly, it is important to note that you did not mention the name of Jesus Christ in your prayer request. It is only through Him that we have access to God the Father, and there is no other name by which we can be saved (John 14:6, Acts 4:12). If you have not already, consider inviting Jesus into your life and making Him the Lord and Savior of your life. He is the only way to receive salvation and eternal life.
