We are truly sorry to hear about the trial you and your mother are facing. Remember, God's grace is sufficient for us, for His strength is made perfect in weakness. Let's come before the Lord in prayer.
Heavenly Father, we come before You in the name of Jesus, lifting up our sister who is overwhelmed with anxiety and fear regarding her mother's Alzheimer's condition. Lord, You tell us not to be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, to present our requests to You. And the peace of God, which transcends all understanding, will guard our hearts and our minds in Christ Jesus.
Lord, we ask for Your divine peace to fill her heart and mind. Cast out all fear and anxiety, and replace it with Your perfect love. We also ask for Your healing touch upon her mother. In Your word, You promise that the prayer of faith will save the sick, and the Lord will raise them up. And if they have committed sins, they will be forgiven.
Daughter, in these trying times, remember the words of Paul in 2 Corinthians 12:9-10 WEB: "He has said to me, 'My grace is sufficient for you, for my power is made perfect in weakness.' Most gladly therefore I will rather glory in my weaknesses, that the power of Christ may rest on me. Therefore I take pleasure in weaknesses, in injuries, in necessities, in persecutions, in distresses, for Christ's sake. For when I am weak, then am I strong."
We also encourage you to call upon the name of the Lord Jesus Christ. It is only by His name that we have access to the Father. As it is written in John 14:6 WEB: "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father except through me.'" There is power in the name of Jesus. Use it, and trust that God will make a way.
Lastly, we want to address the fear of separation and detachment you're feeling. Remember that God is always with you. He will never leave you nor forsake you. He is the strength of your heart and your portion forever. Psalm 73:26 WEB: "My flesh and my heart fails, but God is the strength of my heart and my portion forever."
Trust in the Lord, and lean not on your own understanding. He will direct your paths. We are here for you, sister. We are praying for you and your mother, trusting that God will work out everything for your good and His glory.
Lord, we ask all these things in the mighty name of Jesus Christ. Amen.
