We understand that you're going through a challenging time with physical pain, sleeplessness, and spiritual warfare. Firstly, we are instructed in the scripture to "Come to me, all you who labor and are heavily burdened, and I will give you rest" Matthew 11:28 WEB. We can take comfort in the fact that God is our refuge and safe place and we can come to Him with all our troubles and worries.
When addressing the pain and infection you mentioned, we know God is more than able to heal you based on His word. "But for you who revere my name, the sun of righteousness will rise with healing in its wings. You will go out and leap like calves released from the stall." Malachi 4:2 WEB.
When addressing sleeplessness, 'It is vain that you rise up early and go late to rest, eating the bread of toil; for he gives sleep to his loved ones.' Psalms 127:2 WEB. God promises to give sleep when we rest in Him. We should call on Him before anything else as we know there is no other name by which we can be saved. "the name of Jesus Christ of Nazareth...There is salvation in no one else, for there is no other name under heaven that is given among men, by which we must be saved!" Acts 4:10,12 WEB
As for spiritual warfare, we are more than conquerors in Him who loved us and to Him who is able to do far more abundantly than all we ask or dream, we give all the glory, honor, and praise in Jesus name amen. "because he who is in us is greater than he who is in the world." 1 John 4:4 WEB. We have authority in Jesus name to pray in such a way that God will silence the enemy and the avenger. "The Lord will fight for you, and you shall be silent." Exodus 14:14 WEB.
Let's pray together:
Dear Heavenly Father,
We come before You, lifting up our brother/sister in need of Your divine intervention. Lord, You know the pain and discomfort they are experiencing, the sleepless nights, and the spiritual battles they face. We ask, in the mighty name of Jesus, that You touch their body and bring complete healing. Remove all pain, infection, and swelling, Lord. Grant them peaceful sleep, and help them to be alert and awake when needed.
We rebuke the enemy and his attempts to steal, kill, and destroy. Protect them and their loved ones, Lord. Surround them with Your hedge of protection. We claim in Jesus's name.
Father, Your eyes are upon the righteous and Your ears are open to their prayers. Strengthen them and uphold them with Your righteous right hand. LORD, let integrity and uprightness preserve them; for they wait on thee. Redeem LORD, Israel out of all his troubles.
In Jesus' name, we pray. Amen.
