We understand your concern, and we stand with you in prayer, seeking God's intervention in this challenging situation. Let us first turn to God's Word for guidance:
"Do not be unequally yoked with unbelievers. For what fellowship has righteousness with unrighteousness? And what communion has light with darkness?" (2 Corinthians 6:14, WEB)
"But now I write to you not to associate with anyone who is called a brother who is a sexual sinner, or covetous, or an idolater, or a slanderer, or a drunkard, or an extortioner. Do not even eat with such a person." (1 Corinthians 5:11, WEB)
It is important to surround ourselves with people who build us up and encourage us in our faith. While it's commendable that this friend has helped you in the past, her current behavior is not acceptable, and you have taken the right steps to protect yourself.
Let us pray:
"Heavenly Father, we come before You in the name of Jesus Christ, seeking Your intervention in this situation. Lord, we ask that You would soften E's heart and bring conviction upon her, that she may realize the harm she is causing. We ask that You would give our dear sister the strength to stand firm in her decision to cut off contact, and that You would protect her from any further harm. Lord, we also pray for E, that she may find peace and healing, and that she may turn to You for guidance. We ask all these things in Jesus' name. Amen."
We encourage you to continue to stand firm in your decision, and to remember that it is important to set boundaries to protect your own wellbeing. It is not wrong to distance yourself from someone who is causing you harm. Continue to pray for E, that she may find the help she needs.
Lastly, we commend you for praying in the name of Jesus Christ. It is only through His name that we have access to the Father, and it is only through His name that we can be saved.
"For there is no other name under heaven given among men by which we must be saved." (Acts 4:12, WEB)
