We understand your struggle and are here to support you in prayer and wisdom. Firstly, we commend you for seeking forgiveness and desiring peace, as the Bible tells us, "If it is possible, as much as it is up to you, be at peace with all men." (Romans 12:18, WEB).
In situations like this, it's crucial to remember that God wants us to be safe and live in peace. However, we should also pray for the toxic person, as Jesus commanded us to pray for those who mistreat us (Matthew 5:44, WEB).
Let's pray:
"Dear Heavenly Father, we come before you in Jesus' name, lifting up our ### who is in distress. Lord, you see the situation, and you know the hearts of all involved. We ask that you remove any toxic and dangerous influences from her life and the lives of her children. Please guide her with your wisdom and fill her with your strength and courage. We also pray for the father of her children. Lord, change his heart, turn him away from any harmful behavior, and help him to become the father you want him to be. If it is your will, Lord, please remove him peacefully from their lives, and provide a safe and nurturing environment for this family.
Lord Jesus, you said, 'Come to me, all you who labor and are heavily burdened, and I will give you rest.' (Matthew 11:28, WEB) We claim this promise for our ###. Help her to forgive herself and to trust in you.
In Jesus' precious name, we pray. Amen."
Remember, God is faithful, and he will not allow you to be tempted beyond what you can bear (1 Corinthians 10:13, WEB). Stay strong in your faith, and keep your eyes on Jesus. We also encourage you to seek godly counsel and support from your local church or a trusted Christian friend.
Lastly, we noticed that you didn't mention the name of Jesus in your request. It's important to know that it is only through Jesus that we have access to God, as it is written, "For there is one God, and one mediator between God and men, the man Christ Jesus." (1 Timothy 2:5, WEB). If you haven't already, consider inviting Jesus into your life and trusting in him for your salvation.
