We are truly heartbroken to hear about your situation and the trials you are facing. First, we want to remind you that you are not alone, and that God is always with you, even in the most difficult of times. As it says in Psalm 34:18 WEB, "Yahweh is near to those who have a broken heart, and saves those who have a crushed spirit."
We want to address the issues you've presented, and also remind you that it is only in the name of Jesus Christ that we have access to God. It is by His name that we can approach the throne of grace with confidence. 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.'"
Regarding your diagnosis and that of your daughters, we want to encourage you to trust in God's healing power. He is able to do exceedingly abundantly above all that we ask or think (Ephesians 3:20 WEB). Remember, God is the ultimate healer. Psalm 103:2-3 WEB, "Bless Yahweh, my soul, and don’t forget all his benefits; who forgives all your sins; who heals all your diseases". We pray for your complete healing and that of your daughters in Jesus' name.
Concerning your grandson, we understand your heartache. It is important to trust God in this situation and to pray for His intervention. 1 Peter 5:7 WEB, "Casting all your worries on him, because he cares for you." We pray that God will move in this situation and that your grandson will be returned to you if it is His will.
Regarding the disability benefits, we encourage you to continue applying and appealing. It is your right to advocate for yourself and your daughters. God will provide for you. 2 Corinthians 9:8 WEB, "God is able to make all grace abound to you, that you, always having all sufficiency in everything, may abound to every good work."
We must also address the issue of other preachers saying that your situation needs an exorcist. While we believe in the spiritual realm and the power of deliverance, it is important to approach this topic with caution and much prayer. Not every situation is a result of demonic activity. Sometimes, our trials are simply a result of living in a fallen world. We encourage you to seek God's will in this matter and to be discerning.
Lastly, we want to address the feelings of despair and the desire to die that you expressed. We want to remind you that your life is precious to God. He has a purpose and a plan for you. Jeremiah 29:11 WEB, "For I know the thoughts that I think toward you,' says Yahweh, 'thoughts of peace, and not of evil, to give you hope and a future." We pray that God will fill you with His hope and His love, and that He will deliver you from these feelings of despair.
Lord Jesus, we come before You, lifting up our dear sister and her family. We pray for their complete healing from Huntington's disease, and we ask that You intervene in the situation with her grandson. We pray that You will provide for all their needs, including their disability benefits. We pray for strength, peace, and hope to be restored. We ask that You will guide them in all wisdom and discernment, and that You will deliver them from any feelings of despair. We pray that the praise of the glory of Your grace, which You placed on them in the Beloved will be manifested in this situation. We pray that You will shine the light of Your gospel in their lives, and that they will be filled with the knowledge of Your will in all spiritual wisdom and understanding, walking worthy of You, Lord, to please You in all respects, bearing fruit in every good work, and increasing in the knowledge of God. We pray all these things in Your holy and mighty name, Jesus Christ. Amen.
