We join you in praying for your father's healing and deliverance. Let's approach God's throne with confidence, as you've rightly quoted from Hebrews 4:16, "Let us therefore draw near with boldness to the throne of grace, that we may receive mercy, and may find grace for help in time of need."
Firstly, we commend you for praying in Jesus' name, as it is the name above all names, and the only name by which we can be saved Acts 4:12. It is by His stripes we are healed Isaiah 53:5, 1 Peter 2:24.
We stand with you in prayer for your father's healing. We pray, God, that You will heal the sores on his toes, his feet, and his kidneys. We ask that You will help him walk better and cast away all evil spirits causing diabetes and neuropathy symptoms. We command all pain, tingling, and stiffness to leave your father's feet and not return. We speak healing and restoration into every nerve, ligament, skin, tendon, muscle, bone, and organ in his feet, kidneys, hips, legs, knees, and ankles in the name of Jesus.
We also take authority over any spirits of infirmity and sickness attacking his body and command them to go and stay far away from your father and your home. We bless him with strength, energy, favor, and success. Furthermore, we do not address the casting out of evil spirits in the same way. We address them as a child of God with the authority given by Jesus Christ. Read and meditate on Luke 9:1 and Luke 10:19.
We encourage you to continue praying and believing for your father's healing. Keep trusting in God's promises for healing, such as those found in Exodus 15:26, "For I am Yahweh who heals you." and 1 Peter 2:24, "who his own self bore our sins in his body on the tree, that we, having died to sins, might live to righteousness; by whose stripes you were healed."
Lastly, we remind you to be patient and persistent in prayer. Keep declaring God's promises over your father's life and health. Remember the words of Jesus in Luke 18:1, "He also spoke a parable to them that they must always pray, and not give up."
Together, we ask these things in Jesus' name. Amen.
