We understand your concern for your husband Peter's health and we join you in seeking God's healing power. Let's bring this before the Lord together, in Jesus' name.
Firstly, we want to remind you of God's promise in Psalm 103:2-3 (WEB), "Praise Yahweh, my soul! Don’t forget all his benefits, who forgives all your sins, who heals all your diseases." God is a healing God, and we can trust Him with Peter's health.
However, we also want to encourage both of you to seek God's will in this situation. Sometimes, God uses physical ailments to draw us closer to Him, to teach us to rely on Him more fully. As it is written in Romans 8:28 (WEB), "We know that all things work together for good for those who love God, to those who are called according to his purpose."
Let us pray:
"Father God, we come before you in Jesus' name, lifting up Peter to you. We ask for your healing touch upon his left thigh muscle and the nerve damage. We pray for complete healing and restoration, in accordance with your will. Please give him and Anonymous the strength and patience to endure this trial, and draw them both closer to you. Help them to trust in you completely, knowing that you work all things together for good for those who love you. In Jesus' name, we pray. Amen."
Lastly, we want to encourage both of you to continue to seek God's face together, to pray together, and to trust in Him. As Psalm 34:18 (WEB) says, "Yahweh is near to those who have a broken heart, and saves those who have a crushed spirit." He is near to you both, and He hears your prayers.
