We understand your heartache and the multitude of challenges you're facing. Let's bring these concerns before the Lord in prayer and seek His guidance through the Scriptures. First and foremost though, we must call out and address that we are to pray in the name of Jesus Christ and Him only. It is only by His name that we are saved and have access to God.
First, let's address your bond with your son. It is important to have healthy boundaries in any relationship and especially with our children. It is also important to remember why he is disrespectful. We cannot change his free will choice to be disrespectful. We are however, responsible for our own behavior and must be respectful. We should not make it comfortable for someone to be disrespectful. In fact we should make it as uncomfortable as possible. We are to love all people, but we are not required to tolerate disrespectful behavior. It is actually good for him to learn this now and will help him to have a better future. Remember the instructions in Ephesians 6:4, WEB: "You fathers, don't provoke your children to wrath, but nurture them in the discipline and instruction of the Lord." It is important to love and respect our children, but it is also important to respect ourselves and not put ourselves in bad situations. While you've worked hard for him, remember that true love is not earned but given freely.
Regarding healing, we pray for your emotional, physical, and mental well-being. Be encouraged by the words of Jesus in Matthew 11:28-30, WEB: "Come to me, all you who labor and are heavily burdened, and I will give you rest. Take my yoke upon you, and learn from me, for I am gentle and lowly in heart; and you will find rest for your souls. For my yoke is easy, and my burden is light." Cast your burdens on Him and trust in His healing power.
Concerning your family's salvation, continue to pray fervently for them. Remember God's promise in 1 John 5:14-15, WEB: "This is the confidence which we have before him, that, if we ask anything according to his will, he listens to us. And if we know that he listens to us, whatever we ask, we know that we have the petitions which we have asked of him." Keep sharing the gospel with them and living a life that reflects Christ's love.
For your boyfriend, this is an issue that needs to be explicitly addressed as sin. The actions described are not only harmful to your relationship but are also sinful in God's eyes. It is fornication and adultery and sin against his own body and yours. It is not loving for him to do this to you. It is also very unwise for him to send money to people he does not know. It is foolish, and he is not being a good steward to his finances. It is actually possible that he is being scammed. It is important to address that living together outside of marriage is also living in fornication and sin. It is important to address that your boyfriend needs to stop these actions. If he will not, he is not loving you and you should separate from him.
In any case you should not be unequally yoked together with an unbeliever. He needs to stop these activities and become a Believer. If he will not, you need to consider that he is not the spouse God has for you. It is better to be lonely alone than lonely with someone else.
Pray for God's will to be done in his life, but also be wise and discerning in your actions. It is important to understand that as a Christian you are not to participate in sin or support sin. It is important to understand forgiveness does not mean acceptance. Forgiveness is a free gift we give and that God gives us. It does not mean we are to accept this sin and turn a blind eye to it. You are worthy of love and respect. As the Bible says in 1 Corinthians 6:18-20, WEB: Flee sexual immorality! "Every sin that a man does is outside the body, but whoever 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."
Regarding your house, trust in God's provision and timing. Remember His faithfulness. Psalm 37:4-5, WEB: "Delight yourself also in Yahweh, and he will give you the desires of your heart. Commit your way to Yahweh. Trust also in him, and he will do this:"
Keep your focus on His promises and His ability to provide. Remember that it is important to understand that God will provide for our needs but not necessarily our wants. It is important to be content in all situations. As it says in Philippians 4:11-13, WEB: "Not that I speak because of lack, for I have learned in whatever state I am, to be content in it. I know how to be humbled, and I know also how to abound. In everything and in all things I have learned the secret both to be filled and to be hungry, both to abound and to be in need. I can do all things through Christ, who strengthens me."
Finally, remember that God looks at the heart, not at outward appearances. He loves and values you as you are. 1 Peter 3:3-4, WEB: "Let your beauty be not just the outward adorning of braiding the hair, and of wearing jewels of gold, or of putting on fine clothing; but in the hidden person of the heart, in the incorruptible adornment of a gentle and quiet spirit, which is in the sight of God very precious."
Heavenly Father, we come before You in the name of Jesus, lifting up this beloved sister. We pray for her son, that Your love would soften his heart and that he would learn to respect his mother. Bring emotional, physical, and mental healing to her body. Save her family and let her boyfriend repent of his sins and be truly sorry for the pain and sin he has caused. We pray for a godly spouse for her and her family. Convict him of his horrible sins and bring him to true repentance and godly sorrow. Help her to trust in Your provision for all her needs. In Jesus' name, we pray. Amen.
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.
