We understand that you're going through a challenging time, but we're here to pray with you and provide biblical encouragement. Firstly we are glad to see you are praying in the name of Jesus. It is so important that you know you have direct access to God. The bible says that we have one mediator between us and God. This is Christ Jesus.
First, let's address the anxiety and worry you're experiencing. The Bible tells us, "Don't be anxious for anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your thoughts in Christ Jesus." Philippians 4:6-7 WEB. Instead of worrying, let's commit your health and financial situation to God in prayer.
Let's pray together:
Dear Lord Jesus, we come before You, lifting up our brother/sister in need. They have been struggling with anxiety and worry, especially as night falls. We ask You to surround them with Your peace, Lord and help them to rest in the knowledge that You are always with them. We ask You to guide them to a solution to their financial situation. We pray for their health, that You would heal and strengthen them. We also pray for their family members, that their hearts would be turned back towards their sibling. Remind them all, Lord, that nothing can separate us from Your love, and that You work all things together for good for those who love You and are called according to Your purpose.
Now, let's address the feeling of abandonment by family members. Your family has abandoned you. Know that even when family fails us, God never will. Psalms 27:10-12 KJV tells us "When my father and my mother forsake me, then the LORD will take me up. Teach me thy way, O LORD, and lead me in a plain path," God can turn this situation around and use it for good. Let's pray that your family members will have a change of heart by the work of the Holy Spirit and that God will provide you with a supportive community, such as a local church family.
Regarding your financial situation, remember that God is our provider. He knows our needs and He cares for us. "Therefore don't 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. But seek first God's Kingdom, and his righteousness; and all these things will be given to you as well." Matthew 6:31-33 WEB. Let's pray that God will open doors for you to have an income and that He will provide for your needs according to His riches in glory.
Lastly, remember that God is faithful. He has promised to never leave us nor forsake us. "Be strong and courageous. Don't be afraid or scared of them; for Yahweh your God himself is who goes with you. He will not fail you nor forsake you." Deuteronomy 31:6 WEB. So let us hold this to be true and trust in the Lord Jesus Christ.
We encourage you to spend time in God's Word, pray consistently, and seek fellowship with other believers. Trust in God, and He will see you through this challenging time. Be sure to be in prayer every day to the Lord as He is the one who will provide the help you need.
