We are truly sorry to hear about the struggles you and your grandmother Dorothy are facing due to her dementia. It's important to remember that even in difficult times, God is with us and cares for us deeply. As it says in Psalm 34:18, "Yahweh is near to those who have a broken heart, and saves those who have a crushed spirit."
Firstly, we want to encourage you to continue showing love and patience to your grandmother. Her actions are a result of her condition, and it's important to remember that she is not acting out of malice. As it says in 1 Corinthians 13:4-7, "Love is patient, love is kind and is not jealous; love does not brag and is not arrogant, does not act unbecomingly; it does not seek its own, is not provoked, does not take into account a wrong suffered, does not rejoice in unrighteousness, but rejoices with the truth; bears all things, believes all things, hopes all things, endures all things." We are called to love in this way and this is our opportunity to practice it.
We also want to address the fact that your request did not mention the name of Jesus Christ. It is only through His name that we have access to God the Father and it is only through faith in Jesus Christ that we can be saved and forgiven of our sins. As it says in John 14:6, "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father except through me.'" And in Acts 4:12, "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved."
Now, let us pray together for your grandmother:
Dear Heavenly Father,
We come before you in the name of Jesus Christ, lifting up our sister and her grandmother Dorothy. Lord, we ask for Your healing touch on Dorothy's mind and body. We pray that You would give the family wisdom and discernment as they care for her, and that You would surround them with Your love and peace. We rebuke the spirit of dementia and command it to leave in the name of Jesus. We ask that You would restore Dorothy's mind and memory, and that You would help her to act like herself again. We also pray for Chrualorelview, that You would heal their heart and give them strength and patience as they care for their grandmother. Help them to remember that even in this difficult time, You are with them and You care for them. We believe in You. We ask all these things in the mighty name of Jesus Christ. Amen.
Lastly, we encourage you to continue praying and trusting in God. He is faithful and He cares for you and your grandmother. Remember the words of Romans 8:28, "We know that all things work together for good for those who love God, to those who are called according to his purpose." Trust in Him, and know that He is working all things together for good.
