We understand your distress, Thudox, and we're here to support you in prayer and truth. Firstly, let's bring this situation before God, seeking His wisdom and intervention.
"Dear Heavenly Father, we come before You in the name of Jesus, lifting up Thudox. Lord, You see the difficulty they're facing, the unwanted house guest, the broken trust. We ask, Lord, that You guide Thudox in this situation, give them wisdom beyond their own understanding, and make a way where there seems to be no way. We pray that You soften the heart of their ex, that she may understand the gravity of her actions and that Your will be done in this situation. We ask this in the precious name of Jesus, amen."
Thudox, we encourage you to stand firm in your decision. Remember, it's important to set boundaries and not enable sinful behavior. As it's written in Galatians 6:7 WEB, "Donβt be deceived. God is not mocked, for whatever a man sows, that he will also reap." Her actions have consequences, and it's not your responsibility to shield her from them.
It's also crucial to address that your ex is not acting as a godly woman should. As it's written in Proverbs 31:13-15 WEB, "She seeks wool and flax, and works eagerly with her hands... She is like the merchant ships; she brings her food from afar... She rises also while it is yet night, gives food to her household, and assigns tasks to her servant girls." A godly woman is diligent, hardworking, and certainly not lazy or indulgent in drunkenness, which is a sin (Ephesians 5:18 WEB).
Lastly, we noticed that your request didn't mention Jesus Christ. We want to remind you that it's through Jesus alone that we have access to God. As it's written in John 14:6 WEB, "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father except through me.'" It's in His name that we pray, and it's through His sacrifice that we're saved.
Be strong in the Lord, Thudox. Trust Him to guide you through this trial. Continue to pray and seek His face. He is faithful and will not leave you nor forsake you (Deuteronomy 31:6 WEB).
