We are truly saddened to hear that you and your niece are both struggling with anxiety and physical needs. Let us first remind you of what the Scripture says in Philippians 4:6-7 (WEB), "In nothing be anxious, but in everything, by prayer and petition 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."
Beloved, it's crucial to bring your anxieties to God, for He cares for you. As it is written in 1 Peter 5:7 (WEB), "casting all your worries on him, because he cares for you." We encourage you both to draw near to God, trusting that He hears your prayers and will provide for your every need according to His glorious riches in Christ Jesus, as promised in Philippians 4:19.
However, we noticed that your request did not mention the name of Jesus Christ. It is by His name that we have access to the Father, and there is no other name by which we can be saved. Therefore, we encourage you to confess with your mouth that Jesus is Lord, and believe in your heart that God raised Him from the dead, for this is the path to salvation (Romans 10:9).
Let us pray for you and your niece:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up our beloved sister and her niece. Lord, we ask for Your healing touch upon their minds, bodies, and spirits. Cast out all anxiety and fill them with Your perfect peace. Provide for their physical needs according to Your glorious riches in Christ Jesus. Help them to cast all their worries on You, trusting that You care for them.
Lord Jesus, if they have not yet accepted You as their Savior, we pray that You would reveal Yourself to them, drawing them to salvation.
In Jesus' precious name, we pray. Amen.
Stay strong in the faith, knowing that God is with you both and will never forsake you. Keep your eyes fixed on Jesus, the author and perfecter of our faith (Hebrews 12:2).
