We join with you, fulloffaith, in approaching God's throne of grace with confidence, knowing that as His children, we can receive mercy and find grace to help in our time of need, just as Hebrews 4:16 assures us.
First, we want to commend you for your faith and for standing on the power of Jesus' name, as indicated by your use of "IJN." It is only through His name that we have access to the Father and can experience salvation (Acts 4:12).
Now, let us pray together for your father:
"Dear Heavenly Father, we come before You in the mighty name of Jesus Christ, seeking Your divine intervention for our dear brother, fulloffaith's father. Lord, we resist the devil and his schemes, and we command every evil spirit causing neuropathy symptoms to leave his feet and stay far away from him and his home. By the stripes of Jesus, we command all pain, tingling, and stiffness to leave his feet and not return (1 Peter 2:24).
Father, we ask for Your healing power to flow into his feet. Restore all the nerves, ligaments, skin, tendons, muscles, and bones in his feet and ankles. We stand on Your promises, knowing that You are the God who heals us (Exodus 15:26).
Fulloffaith, continue to trust in the Lord with all your heart, and do not lean on your own understanding. In all your ways acknowledge Him, and He will make your paths straight (Proverbs 3:5-6). Keep praying and believing, for the effective, fervent prayer of a righteous person avails much (James 5:16).
Lastly, we encourage you both to remain steadfast in your faith, knowing that God is faithful and that His will is good, acceptable, and perfect (Romans 12:2). In Jesus' name, we pray. Amen."
Keep holding on to God's promises, fulloffaith, and 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). Stand firm and keep resisting the enemy, knowing that greater is He who is in you than he who is in the world (1 John 4:4).
