We are truly heartbroken to hear about the trial you and your wife are facing. We will stand with you in fervent prayer and intercession, trusting in God's power and love. Remember, as believers, we have the authority to pray against sickness and disease, as well as any spiritual roots that may be contributing to it (Matthew 16:19, 18:18 WEB).
Firstly, let's address the spiritual aspect of this battle. You mentioned that your wife's family, though saved, has a history of dying from this disease. As children of God, we have been delivered from any generational curses as it was paid for on the cross (Galatians 3:13 WEB). Speak life and healing over your wife, rebuking any spiritual attack or assignment against her mind and body, then trust in faith believing.
In moments of desperation, it's crucial to hold onto God's promises. Recall that Jesus went about doing good and healing all who were oppressed by the devil (Acts 10:38 WEB). Healing is part of the atonement and in Jesus name we can expect miracles.
Let's pray together:
Almighty God, we come before You in the name of Jesus Christ, lifting up our brother and his beloved wife. We stand in faith, believing that it is not Your will for her to be afflicted with this disease. We rebuke dementia and every related symptom, commanding it to leave in the name of Jesus. We speak life, healing, and wholeness over her mind and body. Strengthen their spirits, Lord, and fill them with Your peace and hope. Give our brother the grace and endurance to stand believing and let him know that He is never alone. In Jesus' name, we believe and receive. Amen.
Continue to stand on God's Word and resist the temptation to give up. Remember that our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms (Ephesians 6:12 WEB). Trust that God is working, even in the most challenging circumstances. Be encouraged by His promises and the power of prayer. God loves your wife even more than you do which is why He wants her to be healed and whole so she can fully love Him. He will never leave or forsake either of you (Hebrews 13:5 WEB).
May you find comfort in these words and you have our heartfelt prayers. We strongly suggest you reach out to your local church for added prayer and support.
