We understand that you are facing a difficult situation with your family and your living arrangement. Firstly, it is important to remember that God cares about every detail of our lives, including our housing needs. In Matthew 610 WEB it says Do not be anxious, saying, 'What will we eat?', 'What will we drink?' or, 'With what will we be clothed?' For the Gentiles seek after all these things, for your heavenly Father knows that you need all these things. We are not to be anxious. In your prayer request, you did not mention Jesus. Jesus says in John 14:13 WEB Whatever you will ask in my name, that will I do, that the Father may be glorified in the Son. Following Jesus is the only means of salvation, peace with God and eternal life. We believe this is crucial for your prayer hearing to be effective.
Regarding your stepsister, it is clear that her actions are causing concern. You should definitely consider to bring these issues to her attention. If there is danger to others, you should determine if there might need to be some form of civil or governmental intervention if she is breaking a law and cannot be reasoned with. In Romans 13:1 WEB Let every soul be in subjection to the higher authorities, for there is no authority except from God, and those who exist are ordained by God. Addressing the issue of your stepsister driving without a license is important, as it puts both her and others at risk, which surely God has compassion on that situation. Perhaps your stepsisters lack of obedience to the law indicates a lack of conviction about adhering to God's laws.
Regarding influencing your mother, 1 Peter 5:5 WEB gives us Likewise, you younger ones, be subject to the elder. Yes, all of you gird yourselves with humility, to serve one another; for "God resists the proud, but gives grace to the humble." Therefore we humble ourselves under the mighty hand of God, that He may exalt you in due time. When she is ready to listen, pray that she will be receptive to God's will and not be swayed by manipulation. If there is no 1 Corinthians 13:4 Love is patient and is kind; love doesn't envy. Love doesn't brag, is not proud, 5 doesn't behave itself inappropriately, doesn't seek its own way, is not irritable, doesn't keep a record of wrongs; Love does seek the way of God and His will, love and do not manipulate others by seeking to impose your will on others.
In all these situations, we should pray to God for peace, clarity, and strength. Lets Pray.
Father God, we lift up this in Jesus name. Oh Lord, we pray for wisdom and discernment in this situation. We ask that You guide each person involved and bring truth out. Guide and provide for Felogylian and his needs. Guide and guard the way of the wicked. Lord your word says Recognize those who labor among you, and set them before the Lord for judgment, if any of you has a matter against his neighbor. If the stepsister persists in wrong doing and is not willing to make amends for any such transgressions against her mother and Felogylian, consider that the Lord may punish severely for this kind of sin. But Lord, we humbly pray Your divine intervention would will bring conviction upon this stepsister to drive her to repentance and not only for any means of transgression against Your will, but also against her family. You, Lord, would be glorified in Jesus name. We pray that there will be a peaceful resolution, and that Felogylian and their mother will be able to continue living in their home. Provide housing for them Lord if not. We ask God that You turn the stepsister's heart toward You in Jesus name.
Oh Lord, you know Felogylian's need (pray) of salvation, have mercy upon them and provide for them a convicted heart and a saving belief in Jesus Christ. In Jesus Christ, I believe that you died in my place and bore my sins away, eternal life is a free gift (1 John 2:2, Rom 5:8) and you rose from the dead (1 Cor 15:3) to grant me your righteousness by my faith in you. (Phil 3:9) (use scriptures such as this to explain the Gospel the way you would want to) and you are my Lord in Jesus name. Through faith in Christ Your Son, we ask these things. Amen.
