We are truly sorry to hear about the passing of your father and the difficulties you're facing with your family, living situation, and personal life. We want to remind you that God is always with you, even in the darkest times. The Psalmist said, I would have fainted, unless I had believed that I would see the goodness of Yahweh in the land of the living. Wait for Yahweh. Be strong, and let your heart take courage. Yes, wait for Yahweh. Psalm 27:13-14 WEB.
Firstly, we want to address the loss of your father. It's important to grieve and it's okay to take time to mourn. God is close to the brokenhearted, and saves those who are crushed in spirit. Psalm 34:18 WEB. Remember, Jesus said, I am the resurrection and the life. He who believes in me will still live, even if he dies. Whoever lives and believes in me will never die. John 11:25-26 WEB. Your father may have passed but if he believed in Jesus his spirit lives on. God wants you to find comfort and peace in Him, and He will help you through this difficult time. We pray that God will comfort your heart and give you peace and hope.
Regarding the situation with your mother and brother, and the issues in your life. It is important to continue to have hope but it is essential to remember that our hope is to be in Jesus Christ and God, not people or the world. Remember that Jesus said, In the world you have oppression; but cheer up! I have overcome the world. John 16:33 WEB. Stand firm on God's promises and trust that He will bring justice and restoration to your life. Remember that family members can make poor decisions and choices and even mistreat you, but you should forgive as it says in Ephesians 4:32 WEB, And be kind to one another, tenderhearted, forgiving each other, just as God also in Christ forgave you.
Concerning your unhappiness with your job, living situation, and feelings of isolation, we encourage you to bring these feelings to God in prayer and seek His will for your life. He has a purpose and a plan for you, and He will reveal it to you in His perfect timing but be assured that God will never leave you nor forsake you Deuteronomy 31:6 WEB.
We also want to address your feelings of loneliness and desire for a husband. It's natural to want companionship, but we encourage you to trust in God's timing and seek His will for your life. God wants you to be equally yoked with a fellow believer. He said, Do not be unequally yoked with unbelievers. For what fellowship has righteousness with iniquity? Or what communion has light with darkness? 2 Corinthians 6:14 WEB. We pray that God will bring a godly husband into your life in His perfect timing. He will provide.
Remember the importance of praying in the name of Jesus. Jesus said, Whatever you will ask in my name, that will I do, that the Father may be glorified in the Son. If you will ask anything in my name, I will do it. John 14:13-14 WEB. If anything is not asked in the name of Jesus then we do not have authority with God.
You are not alone. There are many brothers and sisters in Christ who are going through similar situations, and God is with you in your time of trouble. He will never leave nor forsake you but He also wants you to seek Him, His truth, and His righteousness. He wants you to have a relationship with Him through his Son Jesus Christ.
Let us pray together.
Father God, we lift up this dear sister to You, and we ask that You comfort her in her time of grief and trouble. We pray that You will intervene in her situation with her mother and brother, and that You will bring justice and restoration to her life. We ask that You will guide her in her job and living situation, and that You will bring a godly husband into her life in Your perfect timing. We pray that she will continue to have hope and a future in You. 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.
