We are truly sorry to hear about the struggles you are facing, and we are here to pray and provide biblical guidance for you. Firstly, it's important to remember that God cares for you and knows your needs. In Matthew 6:25-34 WEB, Jesus teaches us not to be anxious about our lives, what we will eat, or what we will wear. He reminds us that our heavenly Father knows that we need all these things. But first, seek God’s Kingdom, and his righteousness; and all these things will be given to you as well.
Regarding your financial distress, we pray that God will provide for your needs and guide you to manage your finances wisely. Remember the words of Paul in Philippians 4:19 WEB, "My God will supply every need of yours according to his riches in glory in Christ Jesus." Also, consider the words of Proverbs 3:5-6 WEB, "Trust in Yahweh with all your heart, and don’t lean on your own understanding. In all your ways acknowledge him, and he will make your paths straight."
Concerning your living situation, we need to address that living together outside of marriage is not in accordance with biblical principles. In 1 Thessalonians 4:3-5 WEB it says, "For this is the will of God: your sanctification, that you abstain from sexual immorality, that each one of you know how to possess himself of his own vessel in sanctification and honor, not in the passion of lust, even as the Gentiles who don’t know God." We encourage you to consider God's plan for relationships and marriage.
We also want to address the health concern you mentioned. While we pray for your healing, we also want to remind you that God's love for you is unfailing, and He is with you in this challenging time. In Psalm 34:18 WEB, "Yahweh is near to those who have a broken heart, and saves those who have a crushed spirit."
Finally, we notice that your request does not mention the name of Jesus Christ. It is only by His name that we have access to God. In John 14:6 WEB, Jesus said, "I am the way, the truth, and the life. No one comes to the Father, except through me." We encourage you to put your faith in Jesus Christ, as He is the only way to salvation.
Let us pray for you:
Heavenly Father, we come before You, lifting up our sister in need of Your divine intervention. Lord, You know her struggles and the pain she is going through. We pray for a financial miracle, that You would provide for her needs according to Your riches in glory. Guide her in managing her finances wisely and open doors of opportunity for her.
We pray, too, against the betrayal and hurt she feels, and we ask for your will in this living situation. We ask for her to be sensitive to the Holy Spirit and heed the Word of God and his will in her life.
Lord, we also pray for healing, both physical and emotional. Comfort her and remind her of Your unfailing love.
Finally, Lord, we pray that she would come to know Jesus Christ as her personal Savior, that she would put her faith in Him and be saved.
We pray all these things in the mighty name of Jesus Christ, Amen.
Be encouraged, and know that God loves you and is working things out for your good and His glory.
