We understand that you are seeking prayer for your health, specifically regarding diabetes, and that you're asking for God's mercy and intervention. We will lift you up in prayer and also provide some biblical encouragement and guidance.
Firstly, let's pray together:
" Heavenly Father, we come before You in the name of Jesus Christ, asking for Your healing touch upon our beloved friend who is battling diabetes. We ask that You guide their doctors and bring swift healing. We rebuke the spirit of infirmity and speak life and health in Jesus' name. We also pray that You would draw them closer to You during this time, and that they would find comfort and peace in Your presence. We ask this in Jesus' name, Amen."
We're glad that you mentioned the mighty blood of Jesus, which was shed for our redemption and healing. As it is written in Isaiah 53:5 (WEB), "But he was pierced for our transgressions. He was crushed for our iniquities. The punishment that brought our peace was on him; and by his wounds we are healed."
However, we noticed that you mentioned "Your mighty Blood and Fire is Against them all." While we understand the sentiment, we must remember that God desires all people to turn to Him and be saved, as it is written in 2 Peter 3:9 (WEB), "The Lord is not slow concerning his promise, as some count slowness; but he is patient with us, not wishing that any should perish, but that all should come to repentance." Therefore, let's focus our prayers on seeking God's mercy and salvation for all, rather than against them.
Lastly, we want to encourage you to continue trusting in God, even in this difficult time. Remember the words of Psalm 62:5-7 (WEB), "My soul, wait in silence for God alone, for my expectation is from him. He alone is my rock and my salvation, my fortress. I will not be shaken. My salvation and my honor rest on God. The rock of my strength, and my refuge, is in God."
Keep holding on to Jesus, for He is the source of our hope and healing. If you haven't already, consider sharing your faith in Jesus with others, for "if you will confess with your mouth the Lord Jesus, and believe in your heart that God raised him from the dead, you will be saved" (Romans 10:9, WEB).
Prayer Focus: God, Thank You for loving me. Thank You for loving me, Jesus. God, I ask You in Jesus’ name bless me with everything that I stand in need of and everything You want me to have. Bless me to know You in truth, fall in love with You with all my heart, soul, mind, and strength and never fall out of love with You. Bless me to have an ever growing closer stronger, more intimate relationship with You. Bless me with the love, desire, strength, and the spirit of obedience to always delight myself in You, seek first Your kingdom, and Your righteousness. Help and strengthen me God to always respect and obey You. Bless me to trust You with all my heart, acknowledge You in all my ways, and lean not to my own understanding.
