We are truly saddened to hear about the trials you are facing. We want to remind you that even in the darkest times, God is with you, and He has a plan for your life. Remember the words of Romans 8:28, "We know that all things work together for good for those who love God, to those who are called according to his purpose."
Firstly, let's address the living situation. It's understandable that you feel uncomfortable sharing a bathroom with men and being surrounded by behaviors that do not honor God. The Bible tells us in 1 Corinthians 6:18-20, "Flee sexual immorality! 'Every sin that a man does is outside the body,' but he who commits sexual immorality sins against his own body. Or don't you know that your body is a temple of the Holy Spirit who is in you, whom you have from God? You are not your own, for you were bought with a price. Therefore glorify God in your body and in your spirit, which are God's." It is crucial to flee from situations that may lead you to sin or affect your walk with Christ.
Regarding the spiritual warfare you're experiencing, remember what Ephesians 6:12 says, "For our wrestling is not against flesh and blood, but against the principalities, against the powers, against the world's rulers of the darkness of this age, and against the spiritual forces of wickedness in the heavenly places." Put on the whole armor of God, and stand firm against the schemes of the devil.
It's concerning that you mention witchcraft. As believers, we are called to stay away from such practices and trust in the power of Jesus Christ. As Deuteronomy 18:10-12 warns, "There shall not be found with you anyone who makes his son or his daughter to pass through the fire, one who uses divination, one who practices sorcery, or an enchanter, or a sorcerer, or a charmer, or a consulter with a familiar spirit, or a wizard, or a necromancer. For whoever does these things is an abomination to Yahweh."
We need to address the absence of mentioning the name of Jesus in your prayer. It is only through His name that we have access to God. "For 'whoever will call on the name of the Lord will be saved.'" Romans 10:13. We encourage you to keep your faith in Jesus Christ, for there is no other name by which we can be saved. Acts 4:12 says, "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved!"
Let's pray together:
Dear Heavenly Father,
We come before You, lifting up our sister who is going through a trying time. Lord, we ask for Your divine intervention in her life. Provide her with a safe and respectful place to live, away from the influences of drugs, alcohol, and sexual sin. Give her the strength to flee from temptation and to stand firm against the schemes of the devil.
We rebuke the spirit of witchcraft that has been affecting her life. Lord, bind the forces of darkness and release Your peace and protection upon her.
We also pray for her financial situation. Lord, provide for her needs according to Your riches in glory. Help her to trust in You and not be anxious about anything.
Father, we ask all this in the mighty name of Jesus Christ, our Lord and Savior. Remind her of the victory we have in His name and the power of His blood. Strengthen her faith and fill her with Your Holy Spirit.
Amen.
Keep holding onto your faith. Romans 5:3-4 says, "Not only this, but we also rejoice in our sufferings, knowing that suffering works perseverance; and perseverance, proven character; and proven character, hope." This time will pass, and you will come out stronger and more reliant on God. Do not lose hope. Continue seeking God's will and trust in His timing.
Prayer Focus: God, Thank You for loving me. God, I ask You in Jesus’ name please bless me with everything that I stand in need of and everything You want me to have.
